Lately, there’s been a relentless buzz about your neighbourhood’s superhero– Spiderman– as he calls himself. He dons a mask and a red-and-blue tight suit with black webbings all over, and he maneuvers through the city using his web that comes out of his wrists.
He’s the talk of the town because not only does he look cool, he perfectly saves everyone who needs his help. Children, women, men, the elderly. You name it, he saves them from accidents, criminals, and all kinds of dangers lurking in the city.
But no one knows who the person is behind the mask. There have been endless speculations and theories on social media, TV, and newspapers. But no one seems to arrive at a conclusion without any solid evidence. No one knows the boy behind the Spiderman persona. No one except you.
Spiderman is none other than Nagi Seishiro– your classmate, your childhood best friend and most importantly, your boyfriend. His alter ego is a secret shared between just the two of you.
It all started when Nagi suddenly knocked rapidly at your window one night. You instantly jolted from where you sat on your bed, heart racing as a sense of urgency and panic in Nagi’s knock seeped through the glass.
“What happened?” You asked, right after pulling up the window. A look of concern etched across your face. The worry in your eyes seemed to mirror his uneasiness.
Nagi was sweating profusely and replied in a weak voice, “I got bit by a weird-looking spider.” He held onto the window sill with trembling hands.
“Let’s go to the hospital.” You insisted as you gently held his hands, examining him and the bite on his hand. If a spider bite was making him this sick, you were worried that it might escalate and get worse if there was no medical attention provided to him.
Nagi shook his head. “No… I just need to rest. I feel cold. It’s just a fever.”
“Nagi-” You started to protest but were cut off by him.
“Please. I don’t want to go to the hospital.”
Not in the mood to argue with him considering the state he was in, you reluctantly obliged and let him rest on your bed, nursing him throughout the night to the best of your ability.
The next morning, Nagi felt perfectly fine. Too perfect, actually.
When he had awoken from his slumber, his gaze fell upon you, sleeping soundly next to him. Not wanting to disturb your rest, he slowly got out of bed and examined himself in the mirror because he was feeling a bit too well-rested for someone who just had a fever the prior night.
He already had a good-looking and fit body, as expected from an athlete. But he was stunned to see that his torso and arms were even more chiseled than before. He was feeling perfectly healthy. His brows furrowed in confusion, trying to make sense of the change.
You woke up with a jolt when you felt that his presence was not beside you, but he excitedly called your name before you could even fully sit up from your bed.
“Y/N! Look!”
You turned your head to him and saw him without a shirt, flexing his muscles.Your concerns instantly turned into confusion.
“Nagi? What the hell? Why are you shirtless?” You stood up and grabbed a shirt– his shirt that he had left behind previously– from the closet nearby. “You’re gonna feel cold! Here, wear thi-”
“Look! I got buffer, for some reason.” Nagi exclaimed.
You narrowed your eyes and took a good look at your boyfriend this time and after a few seconds, you finally saw what he was talking about. It wasn’t a drastic change, but it was subtle enough to notice upon closer scrutiny.
“Huh? Wow…” was all you could say in surprise.
Throughout the next few weeks, Nagi discovered more changes happening to him and confided in you every single one of them. It was surreal–and yet exciting–when you suddenly found yourself watching him practice his spider skills a month after that night. Using his web to move from one place to another, crawling on walls that gradually got higher and higher, effortlessly punching things that flew meters away. You thought superheroes only existed in comic books and mangas, but here you are watching a fledgling one, and it’s none other than your very own boyfriend.
Once he felt well-practiced and proficient enough in his new otherworldly skills, he admitted to you that he wanted to use his powers for a noble cause– to make your surroundings a better and safer place.
“I hear you, and that would be amazing. But I can’t help but worry, Nagi. I think it’s going to be dangerous.” You folded your arms and frowned slightly, your voice laced with concern.
“Don’t worry, Y/N. I can handle it. I can handle everything: school, soccer, being Spiderman.” He reassured you with a smile. You can see the determination in his eyes, and you knew it would be fruitless to try to persuade him out of it. A part of you was also proud that your boyfriend wanted to make a positive impact using his powers.
“Spiderman?” You chuckled, amused at the name. “Is that your superhero name?”
“Yeah. Why?” He replied in a deadpan tone.
You chuckled. “Nothing. It’s cute.”
You take a few minutes to ponder on your next response.
“Okay. I trust you. But on one condition.” You stop walking to turn to him, bringing a more serious atmosphere between the two of you.
“You have to stop, or at least take a break, from this vigilante work once I see that it’s dangerous and you’re struggling to juggle everything. Okay? Promise me, Nagi.”
Instead of replying, he hugged you right after you finished. “Thank you, Y/N. I promise.”
You ruffle his hair after he lets go of the hug.
“Good boy. Now let’s go have your favorite lemon tea and some takoyaki.” You smiled at him
“I love you.” Nagi whispered, hugging you sideways as the two of you continued to walk. Somehow, you felt that it would be alright.
It’s been almost a year since Nagi began his part-time career as your friendly neighbourhood Spiderman. You are relieved because so far, everything has been smooth.
Nagi has not sustained any major injuries and has been able to balance school, soccer, and being Spiderman perfectly, as he said he would. And of course, his identity is still kept under the covers.
But everything was about to change when a tiny piece of meteorite containing a symbiote fell down on a spot where you and Nagi were spending time together that fateful night. Neither of you noticed it because of its small size. Unbeknownst to either of you, it sneakily latched itself onto Nagi’s bike when the two of you left the place.
Over the next few weeks, you started to observe some disappointing changes in Nagi’s personality and behaviour. He had become increasingly rude to not only you but also to others, including the teachers and his coach.
He despised studying and absolutely refused to do it when you invited him to your regular study sessions. On the soccer field, he started hogging the ball and fighting with his teammates. When reprimanded by the coach for his behaviour, he stormed out of soccer practice before it ended and eventually stopped attending it, which made Reo angry and disappointed.
He still donned the Spiderman suit to save people, but conflicting emotions swirled within you. You can’t deny that his once noble pursuit has become a toxic habit as he had begun using his superhero duty as an escape from his actual responsibilities: your relationship, his studies, people who cared for him and soccer.
Whenever you or Reo tried to reach out and talk to him about what’s going on, he would dismiss both of your concerns, walking out and going wherever he wants, stating that he has “something more important to do.” Reo has no clue what it means, but you do.
You found it extremely frustrating to not be able to get a hold of Nagi. For the first time, you felt him drifting away from you, and you couldn’t reach him. It hurts to see him slip away and be unable to bridge this growing gap between you and Nagi.
One fateful night, Nagi struggled to get home as he was feeling heavily delirious. Thinking it was just fatigue and fever, he decided to sleep it off, hoping that a good night's rest would make him feel refreshed. In his dream, he saw blurry visions of a glossy black substance that resembles a slime oozing out of his skin, and forming another… Nagi. A clear doppelganger of himself. Though, this counterpart has a sinister aura, bore a devious look on his face, has black hair, and instead of the usual Spiderman suit, this Nagi was clad in black. It didn’t seem like the friendly neighborhood Spiderman Nagi was. The counterpart then vanished in whips of smoke and the dream ended there.
Nagi woke up with a severe crushing migraine and body aches throughout his whole body. Even the simple act of just sitting up on his bed was a labour. He wasn’t sure what time of the day it was, or what even day it was. Fortunately, you walked into his room just in the nick of time. Your presence brought him a glimmer of relief.
“Baby?” He murmurs in a groggy and tired voice.
You quickly took a seat at the edge of the bed. “Nagi… you’re finally awake.” You replied, feeling a mix of relief and concern.
“Finally?” He asked, his brows furrowed in confusion
“You’ve been asleep for three days. Your fever won’t go down until just a few hours ago.” You explained.
“Oh… three days? Wow.” He says, trying to comprehend how fast time had flown and what exactly happened.
“Yes, three days…” You sniffle, startling Nagi and making him look at you right away.“And for the first day of those three days, you weren’t answering my calls and texts. I reached out to you like a hundred times. I was so worried!” You sobbed, spilling over all your bottled-up emotions.
“Oh no. Baby, please don’t cry-” Nagi’s concerns for you deepens.
“Also, it’s like I don’t know you anymore. What happened? Why did you change in just a short amount of time?” You finally look him in the eye, it feels like ages since the last time you were able to do that.
“I.. I don’t know. My mind was just all over the place, I think? I felt… detached. From everyone, from everything.” Nagi struggles to explain, as he himself doesn’t know exactly.
“That’s not an excuse, though.” You frowned. “You hurt me, and others too. I had to constantly apologize to them in your place because I couldn’t bear other people hating you, or talking bad about you.”
“I’m sorry. I’m so sorry, baby. I promise, I’ll make it up to you and to everyone. I’m sorry. Please forgive me.” Nagi pleads, on the verge of tears as he wraps you in an embrace. He has never felt this guilty and distraught ever in his life. You’re the only one who has this effect on him.
“But are you okay now? Is your mind clear? Do you not feel detached anymore like you were saying earlier? You can’t promise things if you can’t deliv-”
“Yes! I’m okay now. Really. I mean, my body is in pain but for some reason, I feel better, lighter. It’s like nothing’s weighing me down anymore.” Nagi assures you.
“We promised to tell each other everything. Why didn’t you?” You cried into his chest, feeling a sense of betrayal.
“Yes, I know. I’m sorry. I’m sorry.” He repeated his apologies, accompanied by gentle caresses on your head to soothe you.
It started out a bit slow at first–with Nagi making reparations and sincerely apologizing to the people he had disrespected–but he eventually came back to his former self. Fortunately, he had always been well-loved and popular among everyone in the school, so it was not very difficult for people to forgive and forget. His genuine efforts to mend and rectify his mistakes worked.
It seemed as if fate had worked its magic and everything seemed as if it was back to normal. Though you should have known that fate always had other plans and something was bound to happen yet again.
While on a date with Nagi in the city, strolling on the bustling streets until your attention was abruptly caught by a piece of urgent news, accompanied by live footage flashed on the huge LED TV mounted on one of the nearby buildings.
The footage displayed a very chaotic scene showing a figure in black, eerily resembling Nagi’s Spiderman both in looks, web-slinging, crawling abilities, and overall movements. The newscaster reported that this person was seen destroying everything they passed by: buildings, statues, and vehicles. The live video recording of this person suddenly panned to the spot where you and Nagi currently are. The black figure is here, and he is eyeing the both of you.
“It… wasn’t a dream?” You hear Nagi whisper to himself as he looks back at the dark enigma with wide eyes.
“Nagi? What’s happening? Is that an impersonator?” You asked, feeling confused. Your grip on his hand tightened and his thumb gently caressed the back of your hand.
The situation escalated as the police arrived. Some officers started evacuating people from the area, while others began shooting the clad-in-black criminal.
“Y/N, go follow the police and evacuate. I need to take care of this. Go home, I’ll see you there.” Nagi urgently says, bringing you to the nearest police officer in charge of the evacuation.
“Take care!” You shout as Nagi runs away quickly to a secluded spot and secretly unravels his casual clothes so he could properly fight in his Spiderman suit.
He barely got out of his hiding spot when the black figure attacked him. You had to hold back from screaming his name in worry, remembering to hide his identity from everyone who could hear you. You gripped your hands tightly, trying to contain your worry and fear.
“Enjoying your date with her, huh?” The villain asks sarcastically with a smirk hidden behind the mask, choking Nagi in the rubble that was caused by his fast attack.
“Who are you?” Nagi manages to ask, his voice strained.
“I’m you… but only made of your dark impulses, tendencies, and desires. I guess you can say I’m the dark version of you, manifested.” The villain revealed in a hauntingly familiar voice.
Nagi couldn’t believe what he was hearing. How is that possible? But the voice and just the existence of this villain proved otherwise. Nagi musters his strength and finally counters his opponent and successfully hurts him. As the battle intensified, Nagi decided to take their fight to an isolated location away from the population to avoid potentially innocent bystanders.
They continue to fight until the dark version of Nagi has to flee due to injuries that Nagi inflicted, but not without leaving a warning. As a goodbye, he removed his mask and told Nagi in a voice thick with malice, “Out of the two of us, I will be the only one left standing. I will be the one alive at the end of this and I will take your place in this world. I’m going to take everything that’s yours, including her.”
Nagi is too stunned to move. Not only had he encountered someone who could be his twin, but now he realises that you are in danger as well.
That night, Nagi tells you everything: his dream, what he had learned about the person who attacked him, including who he said he was and his ominous warning.
“So this… person…” You crossed your arms. “He self-proclaimed that he’s the dark version of you. So, I guess we can call him… Dark Nagi? Kuro Nagi sounds better.” You say. Nagi nods in agreement.
“I need to defeat him as soon as possible, or else he will just be a menace to society again and he will also head for you,” Nagi says with a determined look. His resolve to protect you and everyone else strengthens. “Can’t let that happen.”
Ever since then, Nagi has become more vigilant about his surroundings, what’s happening in the news, and you (where you are when you’re not with him, what you’re doing, who you’re with, what time can you be together again, etc.). He also requested for you to live in his house and sleep in the same bed as him, to ensure your safety. You easily obliged because both of your and his parents are out of the country anyway. It’s nice to find comfort in each other’s presence amidst the danger.
Kuro Nagi has been out of sight for almost a month since his first attack. This did give a brief period of calm. That was until he resurfaced. This time, he goes straight for you.
You were watching Nagi during his after-school practice and had planned to go home together afterwards. You had gone to the restroom for a while and that's when Kuro Nagi seizes the opportunity, sneaking in and kidnaps you.
You wake up feeling disoriented a few hours later and find yourself face-to-face with the man who had fought Nagi. He really did look like your Nagi. All the drowsiness goes away and you're now on full alert. You look around quickly and it seems that you're in a dilapidated house in the forest just outside the city.
"Don't be scared, Y/N. I won't hurt you." He says with a sickeningly genuine smile. It sends shivers down your spine.
You gathered your courage to speak up. "N-Nagi told me everything. Who you are, your plans. I'm scared, but… I also wish to understand you. What are you?" You asked, your voice quivering with fear and curiosity
"You see, I'm a symbiote. A parasite kind of alien who seeks a host and eventually kills that host to take their place. We thrive on our host's dark side. We also get some of our host's memories, that's why I know you, and how important you are to him." He says the last part with a devilish grin, causing you to have chills all over.
"I've been secretly watching the both of you since that fight. Both of you, but especially you." He continues, looking at your figure from head to toe, making you uncomfortable.
"I don't know. I was just intrigued by you. I wanted to see for myself why he likes you so much." He smirks. Your discomfort grows at every passing second.
The unsettling tension gets broken by your ringing phone.
"Oh, your phone's with me." He stands up to get it on the old wooden table. "God, he's been calling nonstop." He rolls his eyes before answering the call.
"She'll be staying with me from now on." Kuro Nagi curtly states, upon bringing the phone to his ear.
"You bastard. What did you do to her?!" You can hear Nagi's muffled angry voice from the other line.
"Nothing! Don't worry, I'm not gonna hurt her. I'll never do that." Kuro Nagi says as he looks at you with a smile. "And besides, why are you so surprised about this? I already told you, I'll take everything that's yours, including her."
You wanted to yell and convey to Nagi that you're in a dilapidated house in the nearby woods but Kuro Nagi ended the call and turned off your phone right after he told Nagi what he wanted to say.
With that, the two of you stayed in that house with him talking to you and asking you tons of questions, and you had no choice but to entertain and answer him out of fear. Hours stretched into what feels like an eternity for you.
Kuro Nagi finds himself feasting on the sight of you, he really enjoys looking at you, talking to you, hearing your voice, and seeing you squirm in his presence. He finds pleasure in having you all to himself. He thinks your scared-but-trying-to-be-tough face is so endearing.
"Appearance and memories are not the only things I share with my host, but also emotions." He suddenly shares the information with you.
"So, since he loves you… I love you too."
You're too stunned to speak. Honestly, you don't know what to say to that at all, so you look away, unsure how to respond to this revelation. He looks like Nagi, was a part of Nagi. Yet, he was a stranger to you.
Kuro Nagi just smiles at you, finding your reaction cute.
It had been around four long days before Nagi finally arrived and found you. Their second round of fight was longer and more brutal. It resulted in you and Nagi barely getting out of there alive. Nagi deduces that Kuro Nagi has been recovering and strengthening himself since their first fight last month.
As you and Nagi were leaving, you locked eyes with the injured and bloody Kuro Nagi until you finally left the area.
Once back in Nagi’s home, you tended to his wounds. The more severe injuries like broken bones and muscles will recuperate on their own with plenty of rest. You shared with Nagi all the crucial intel that you had gathered from Kuro Nagi during your stay in that old house with him.
“Y’know, I kinda feel bad for him.” You admitted, dabbing Nagi’s wound with cotton and alcohol. “He’s all alone there. He’s lonely, and now he’s in pain.” A sense of empathy for the symbiote began forming, even if he was dangerous and a threat.
“He shouldn’t exist in the first place, Y/N.” Nagi reminds you.
“I know. I understand.” You responded, with a small frown.
“You’re too kind.” He says with a tired smile as he caresses your cheek gently.
When the both of you are settled and done cleaning up, you take a very long and peaceful nap together on Nagi’s bed. Wrapped in his arms, you felt safe.
The next morning, you left Nagi a little note telling him that you were going to the grocery to buy supplies, which is just half of the truth. The other half is that you’re also going to Kuro Nagi’s shelter in the forest, despite not being entirely sure that he’s still there.
Branches snapped underneath your shoes as you walked. The aftermath of yesterday’s fight is still fresh. Broken trees, uneven patches of earth, and blood everywhere. Luckily, no civilians witnessed the fight. It’s better for this whole issue to have less exposure, as it might risk your and Nagi’s identities to be revealed. Too messy.
You carefully approach the shack and are about to call out Kuro Nagi when you find him lying down on the makeshift bed by the wall. You quietly rush to him so as not to wake him up and check his temperature. Unlike Nagi, he doesn’t have a fever, perhaps due to his alien nature. But he still has wounds all over his body.
“Y/N?” He calls out weakly while you open the medical kit you purchased from the grocery on the nearby table.
“Y-you’re here?” This time, he tries to open his eyes.
“Yes, I’m here” You responded softly. This situation got you thinking about how Nagi would react if he ever finds out that you went out of your way to tend to his enemy’s wounds.He would probably be mad.
You quickly get to work, wiping his wounds and bloodstains with clean water and towel, then with alcohol and cotton balls. You also stitch up his wounds and cuts, a skill you had to learn and master ever since Nagi became Spiderman. You’re too focused on what you’re doing that you don’t notice Kuro Nagi watching you with heavy-lidded eyes. Honestly, he’d rather sleep and let his body do the work of healing and regenerating. But how could he ask you to leave after all your efforts and trouble to be here? Also, your focused face is too cute, he thinks. It’s a sight he doesn’t mind waking up to.
Truthfully, there’s been something bugging Kuro Nagi lately. Something stirring in his chest since he kidnapped you and had you all to himself during those four days. He’s been ignoring it, but the more time you spend together, the more aggressive it becomes. Whatever it is.
“There. Done!” You chirp with relief, wiping the sweat from your forehead.
“I also brought food and drinks, if you take those. I’m not sure.” You show him the grocery bag and its contents that you had placed on the table.
“Thank you, Y/N.” He says as you clean up and quickly put all the used medical items into the trash bin.
“I’m gonna go now-”
“Stay. Hmm? Please? Please stay.” You hear the desperation in his voice, something you didn’t hear during the past few days you were alone with him. Despite the sympathy you felt for him, you knew you couldn’t stay any longer.
You shake your head, “I’m sorry. I can’t. Nagi is probably looking for me already.” You apologized gently and stood up and got ready to leave.
He scoffs, “Of course, it’s all about him again.” his voice dripping with jealousy and bitterness.
You turn around and walk away briskly. Yes, you did feel bad for him, but his last statement and bitter tone remind you that he’s still the bad guy.
He’s Nagi’s enemy.
And you should never dance with the devil, your boyfriend’s nemesis.
Sometime after the second encounter between the two Nagis, a huge and terrifying monster appeared at the buzzing heart of the city. Nothing of this scale and danger has been seen before. It’s black in colour, glossy, stringy, teeth sharp and long. The black part bears an uncanny resemblance to Kuro Nagi’s suit and the material that Nagi saw in his eerie dream several months ago.
During the onset of the monster’s attack, Nagi is at soccer practice while you’re in the city shopping alone. Both of you are oblivious to the current danger.
Everything is happening too fast within minutes. Buildings and structures are getting dismantled left and right in the wake of the creature’s rampage. Nagi only learns about it when the soccer team are on a quick break and Reo who’s on his phone shows the live footage to him.
“What the fuck is going on in this city, man?!” Reo exclaims, and Nagi does not even answer as he wastes no time sprinting to the location. He knows that you’re there as your original plan was to meet up for dinner in the mall.
His heart is palpitating loudly and non-stop when you don’t answer your phone. He can’t lose you. Panic courses through him.
Meanwhile, you try to run away from the monster as fast as you can, to no avail. One of its strings latches on to you and propels you up in the air just like what it’s doing to its other victims. Nagi, donned in his Spiderman outfit to be precise, comes swinging into the scene and swoops you first.
“How about the rest?!”
“I already created and placed large sturdy webs that will catch them everywhere, don’t worry. The police are quickly evacuating everyone too.” He assures.
Nagi is about to put you down somewhere far and safe when one of the monster’s black strings strikes him, causing the two of you to fall midair. Nagi immediately regains his balance and jumps towards you as you continue to fall. He activated his web so you can hold on to it, but it’s not gonna reach you in time. For a second, your life flashes before your eyes. For the first time, Nagi feels that he might actually lose you as you seem beyond reach.
Until a shadowy figure from your right suddenly flies towards your direction to catch you in midair.
“K-Kuro Nagi?” You ask in shock after he carefully places you down on a spot far from the monster.
“I… gotta help him.” Nagi furrows his brows. “He can’t handle that monstrosity alone. That thing is made from the same parasite as me. But it failed to find a host and has become defective. I need to go.”
“Be careful!” You exclaim as Kuro Nagi swings past you.
Kuro Nagi stands by Spider Nagi’s side and immediately shows him zero hostility when Nagi is about to fight him too. Kuro Nagi tells him what he had told you about the monster, persuading him that they need to work together if they wish to eliminate it.
“Our species’ has two weaknesses: fire and sound of high frequency.” Kuro Nagi begins explaining his plan. “Luckily, there’s a gas truck over there. We can set it up in flames and wait for it to shrink and burn up completely.”
“Alright.” Nagi answers reluctantly, still not fully trusting his former enemy. Though, for the sake of exterminating the creature and the safety of the citizens, Nagi is willing to comply.
They execute the plan and the black behemoth is now in flames. However, after waiting for about two minutes, it has not yet shrunk significantly and is starting to regain energy to destroy.
“It’s not working. We should utilize the other weakness you mentioned. High-frequency sound can be achieved by banging those metal poles together repeatedly.” Spider Nagi points to the metal poles on the streets that fell from the construction site that the monster destroyed earlier.
“What do you think?”
Kuro Nagi takes a while to think before responding, “Yeah. Sure. That might work.”
The two of them swing their way to the metal poles and start erecting them around the monster whose movement has slowed down because of the flames. All the poles have been erected. Right before Spider Nagi starts hitting the poles, Kuro Nagi removes his mask and talks to him, admitting that this strategy will affect him as well and make him disappear.
“Not that you care, exactly. After all that I’ve done to you. But… I’m just saying, you’re on your own from now on. Good luck.” He says, turning around to move away from the scene.
“Where are you going now?” Spider Nagi questions.
“Just… gonna say goodbye to someone.” Kuro Nagi replies cryptically.
“Thanks for the help.” are Spider Nagi’s last words to his evil counterpart, who no longer seems so evil now. He had an inkling as to who the ‘someone’ was.
Nagi waits until Kuro Nagi is finally with you. As much as he wants him to properly say goodbye to you before he disappears, the monster is starting to accelerate again and now is the only time and chance to defeat it.
“Kuro!” You call as soon as he lands on his feet, and by then the high-frequency sound is already audible throughout the area. “What happened?!”
He’s clearly in pain and his black suit is also acting up. Yet, he still stands firm, determined to see you one last time.
“Don’t worry about him. He’ll absolutely defeat that shit. As for me, you don’t have to worry about me lurking around you anymore.” Despite his struggle, he’s still able to smirk at you.
“What do you mean?” You asked. You try to reach out to him but he steps back. Perhaps he didn’t want you to touch his suit as he might have unknowing effects on you.
“This is the last time…” His voice trails off as he groans in pain.
“Kuro!” You cried out in worry.
“Those loud sounds are what’s killing that monster, and me. This is goodbye, babe.” He smiles as he calls you using Nagi’s favourite pet name for you.
“You sacrificed… yourself?” You feel tears welled up in your eyes at the information.
Kuro Nagi nods weakly. “Y’know, I thought I only love you because it’s what my host is feeling. That I just inherited it from him. But I realized that I actually, and surprisingly, learned to love you on my own accord. And it’s no brainer that I don’t deserve you.”
“I wish we could’ve been friends.” You said quietly as you looked at the ground.
“Yeah, that would be nice.” Kuro Nagi responds with a painful smile and tired dreamy eyes looking up at the sky, as if he’s picturing the two of you being the best of friends, picturing what could’ve been.
“But sadly, I’m an anomaly. And I shouldn’t exist.” Kuro Nagi says softly as he wipes your tears away.
You glanced back up to take a good look at him for the last time, and you’re horrified to see that only a quarter of his body is left, just his chest upwards. He’s disintegrating away.
“Thank you for taking care of me that day, even though I didn’t deserve it. You’re too kind. Just be happy, okay?” He smiles at you before completely disappearing, his black suit turning into soot.
You watch Nagi and the monster from afar and see that the latter has become a large cloud of soot as well, disappearing into the atmosphere.
Nagi is far from you but you want to hold him and just be in his arms. Everything has just been so overwhelming. The danger brought by the monster, suddenly losing Kuro Nagi and watching him die. You just miss your Nagi and need his comfort.
He’s tired from the fight but he sees you running to him and meets you halfway. He embraces you and he swings the both of you to a distant rooftop where you can have a moment of privacy all to yourselves.
“Are you okay?” The two of you ask in unison, causing a burst of short-lived laughter.
“You’re dirty, but at least you’re not very bloody and severely injured.” You wipe the dirt and some blood on his face after he removes his mask.
“Yeah, thanks to him. He told me how to defeat that thing.” Nagi says.
Tears trickled down your cheeks. “He’s gone. He died in front of me.” You sobbed.
Nagi holds you in a tight embrace. “Yeah, I know. He said he wanted to say goodbye to you.” He says. You sniffle into his chest as he caresses your hair. He presses a tender kiss on your forehead.
“Shhh…Don’t cry, baby.” Nagi whispers. “Everything will be alright now. We got through it together.” He reassures you.
And you smile, because Nagi’s right. All that had happened has left an impact on both of you, but together, you both managed to overcome it. The two of you spend some time on the rooftop before Nagi swings both of you home as the sun sets.
