thank you to @hobeemin for betaing <3
You’re sitting on the couch with two pairs of legs in your lap. To anyone else, it would look like a sweet scene. Your boyfriends cuddling while you watch them fondly. But you’ve never felt so alone before.
You knew you were the addition to the relationship—San and Wooyoung had been dating for a long while before they met you, and it took another few years for them to ask you to join their relationship. After crushing on the two of them for so long, you had leapt at the chance to.
At first, you were just happy to be there—to have them smile at you sweetly, hold your hand, and press you into the sheets so well. But as time passed, it felt like being there was all you had to be happy about.
Sometimes, you wonder if you had just misconstrued the whole thing. Maybe they just wanted a roommate they could fool around with. Or you’re just reading too much into it. It’s only been six months since you were invited into the relationship.
As you’re contemplating your relationship with the two, your boyfriends stand. You only notice because of the weight leaving your body. “Hey, babe, Sannie and I are going to the bedroom, okay?”
“Oh– is there anything I can do too?” The desperation in your voice is evident, and you hate that it is. San’s eyes soften but both he and Wooyoung chuckle. Not meanly, but not kindly.
“Not today. Enjoy the movie.”
They each drop a kiss on the top of your head, and just like that, you watch them slip right through your fingers again.
You do your best to sit there and not feel upset; you try, but the pinch in your heart doesn’t go away. They’ve never been so outwardly…dismissive of you, and you’ve had quite enough of it. After a long five minutes of unhappy thoughts swirling around your head, you stand. You’re not sitting around and letting yourself feel like the second (or third) fiddle.
You blink back the angry tears threatening to fall as you pull on your sweatshirt and search for your phone, only to remember you left it on the bedside table. You’re not about to barge in on and grab it so you settle with your keys. You won’t be out for too long anyway.
As you leave the apartment, you do your best to close the door behind you as quietly as possible. The crisp fall air clears your mind, and you can think properly about your relationship. You just cannot allow yourself to continue to hurt like this. They’re a package deal to you and will come hand-in-hand with you in your life. You may love them, and they may be fond of you, but in the end, you’re just a plus one.
The realisation hits you like a ton of bricks, and you clap a hand over your mouth to muffle the sob that escapes. It hurts you deeply, and you don’t want it to be true. You want to believe they need you just as much as you need them, although you know the thought is futile.
You shudder as you finally let your sobs calm down, and your heart returns to a normal pace. You can’t stay there much longer if you don’t want to lose yourself. As you head back to the apartment, you hurriedly wipe your eyes and clear your throat, unwilling for San and Wooyoung to see the state you’re in.
But that proves unnecessary—when you walk back in, San is sitting on the couch, a new movie is on the screen, and Wooyoung is prepping dinner. A quick glance at the clock tells you that you’ve been gone for about an hour and a half. Your blood boils as you realise they hardly noticed your disappearance, but you force it back to your gut. Blowing up now would be counter-productive.
Your phone is right where you left it, but as you try to escape, San calls out for you, “Oh, YN. Woo and I wanted to ask…” Your breath catches in your throat, hoping for something. “Do you want to join us next time?”
It takes all of your willpower not to laugh. “No, I don’t think I will.” Such a tone of mockery had never left your mouth directed at them before, and you snap your mouth shut before you say something else. San’s eyebrow rises high into his hairline.
You hear Wooyoung chuckle from the kitchen. “That’s fine. We have more fun without you anyway.”
And you know, deep down, he didn’t mean it maliciously. Wooyoung doesn’t have a mean bone in his body. He was just trying to be funny and lighten the mood from the tension he had heard in your voice. But he didn’t know he (and San) was the cause of the stress, and all he does is relight the anger in your gut.
“Oh, so I’ve realised,” you mutter, and this time, San’s other brow raises, and he interrupts.
“What do you mean by that?” He moves to cross his arms, and you scoff.
“I’m sure you know damn well what I mean, Choi San. I get it. You guys have been dating for…longer than you’ve known me. It’s understandable you guys sometimes just want to be together without me.” You pause to take a breath, and San looks just about constipated. “But…I genuinely cannot remember the last time the three of us went on a date or included me in anything other than just sex. And even that, once in a while. What is the point of me being here?”
“Why didn’t you just talk to us?” Wooyoung asks, having moved from the kitchen to stand in the doorway. His brows are furrowed, and he looks so confused that you almost want to forget your argument. But it’s gone too far already, and words won’t stop pouring out of your mouth.
“You would rethink your already comfortable relationship for me? Don’t be silly.” You cut off Wooyoung’s attempted argument. “Maybe you would’ve thought about it, but come on. I’m me. I’ve known you guys for four years; you’ve been dating for seven. I asked to join you guys all the damn time, but all I got was getting brushed off. Forgive me for not having the confidence to confront you two.”
You run your hand through your hair, blinking back your tears. “I can’t imagine this relationship without you guys, but to you two? I’m just an afterthought,” you state, shaking your head.
Before your soft heart gets the better of you and you fall to your knees and take it all back, you turn right back out the door, your phone clutched in your hands this time. Wooyoung and San make no move to go after you, and it hurts more than it should.
You’re not in the mood to walk and wallow, so you sit in the parking garage, ordering a taxi. As you wait for your ride, you hear footsteps thundering up to you, and you know what’s coming.
“Are you actually leaving?” San’s voice comes from behind you, a tightness to it you haven’t heard before.
You keep your eyes forward and nod. “Yes. I need some time to myself. I…I won’t leave forever, at least not for now. I don’t want to give us up, but I need time to rest my heart. And you guys need time to process, I’m sure.”
The taxi you called is pulling up now, and you stand. After hesitating, you turn around and wrap your arms around San’s waist. There’s no wait on his side; his warm and strong arms come around your shoulders to squeeze you gently. Your eyes are shut tightly, knowing that if you open them, you’ll want to go right back up to the apartment.
“Tell Wooyoung I said ‘sorry’,” you manage to choke out, and you can practically hear San’s melancholic smile.
“You have nothing to apologise for, but I will if it makes you feel better. The only reason he didn’t come down is because he didn’t want to overwhelm you.” San sighs, running a hand through his hair. “For whatever it’s worth, I’m sorry we’ve made you feel so alone. It was never our intention, but that doesn’t excuse the fact that it happened.”
You sometimes wish San wasn’t so sweet and lovely and perfect. And you sure wish Wooyoung didn’t feel as strongly as he did. If they cared less, it would’ve made your hurt and betrayal less sharp in your chest. But you don’t want them to be guilty, and you don’t want Wooyoung to cry.
“I…won’t be gone for long,” is all you have left to say to San before you cram yourself into the taxi, and will your tears to not fall until you get into the safety of your apartment that doesn’t even feel like home.
As soon as you reach your apartment, you collapse to your knees and cry. With every sob, your chest heaves and your throat aches. But you’re finally able to let out all your hurt, and after an hour or so, you feel as refreshed as you can be. You hope it will work out in the end for your sake and theirs.
—
You sink into the familiar comfort of your couch, a sigh escaping your lips as the silence of your apartment envelops you. It's been two weeks since the tearful confrontation with San and Wooyoung, two weeks since you've allowed yourself to feel the full weight of your emotions. The initial relief of expressing your pent-up frustrations has given way to a dull ache of longing and uncertainty.
Days turn into nights, and the silence stretches, punctuated only by the occasional text message from San and Wooyoung, their words a mix of apologies, reassurance, and pleas for you to come back. You read and reread their messages, your heart torn between the desire to run back into their arms and the fear of being hurt again.
Yeosang, your closest friend, becomes your lifeline during this time, his presence a comforting anchor amidst the storm of your emotions. He listens patiently as you pour out your doubts and fears, offering his unwavering support and gentle guidance. "They miss you, you know," he often reminds you softly, his eyes reflecting a deep understanding of your inner turmoil.
"I miss them too," you admit, your voice barely a whisper. "But what if it's not enough? What if we can't bridge the gap that's grown between us?"
Yeosang squeezes your hand reassuringly. "You won't know until you try. They're willing to work on things, YN. Don't let your fear rob you of a chance at happiness."
His words echo in your mind, a constant reminder that you can't stay hidden forever. You need to confront your fears, to have that difficult conversation, and to decide whether the love you share is strong enough to overcome the challenges you face.
As the days pass, you find yourself slowly emerging from the cocoon of your self-imposed isolation. You start venturing out, meeting friends for coffee, taking walks in the park, trying to rediscover a sense of normalcy amidst the chaos of your emotions.
But the longing for San and Wooyoung never truly fades. It lingers in the quiet moments, in the empty spaces beside you on the couch, in the memories that flood your mind when you least expect them.
Finally, after what feels like an eternity, you call Yeosang, asking him to meet up with you for coffee so that you can figure out how to approach your relationship with San and Wooyoung. He agrees readily, and promises to set aside some time at lunch tomorrow to hear you out.
“You miss them, too.” You blink at Yeosang’s statement, before heaving a sigh and taking a sip of your drink. As usual, he doesn’t waste time with small talk and just starts with the point of the meet-up. “You’re putting off this discussion for far too long, YN.”
And he’s right, as he usually is. It’s been about two weeks since the breakdown, and you’ve managed to avoid most attempts at reaching you, placating them with a ‘soon’ whenever they text you to ask. But you’re a little too scared to reopen the conversation. What if they hate you and don’t want you anymore?
“They don’t hate you,” Yeosang interrupts your spiralling with an all-knowing look. You swear he can read your mind, and he swears you’re just easy to read. “You both just need to have a long conversation. Of course, it may not work out properly, but if not, they need to know it for future reference.”
You bite your lip, sighing like the weight of the world rests upon your shoulders. “Stop being so smart, okay? I know I should. I’m just…I don’t know how to start.”
Yeosang raises an eyebrow. “First, you should set up a date to talk. I recommend calling them.” He easily dodges your slap. “Seriously, YN. I can’t tell you what to say. Just go talk to them properly. They’re not gonna be unreasonable. They like you.”
If you sighed anymore, Yeosang would probably smack you himself. “Fine. I’ll call them tomorrow.” Yeosang narrows his eyes, and you know he’s seen right through your lie.
“Call them now. I won’t bother you or be loud.”
You start to whine, but Yeosang fixes you with such a glare that you pull out your phone begrudgingly. Your hands tremble as you dial Wooyoung's number, knowing San would probably be at work right now. The phone rings once, twice, and your heart squeezes in hope and disappointment that he hasn’t picked up yet.
You’re just about to hang up when the phone picks up, and Wooyoung’s breathy voice crackles over the receiver. “Hello? YN?” He sounds like he just ran a marathon, and you can’t help but smile. The sound of his voice on the other end of the line sends a wave of warmth through you, a bittersweet reminder of the love you've been missing.
“Hey, Wooyoung. Sorry for never getting back to you guys.” You can already feel the awkwardness and tension through the phone call. “Uh…when are you guys free to talk?”
You can hear the eagerness in Wooyoung’s voice as he responds almost immediately. “Don’t apologise, YN, okay? San and I are free tonight after five. Would you like to come round to have dinner? I’m making spicy pork belly soup. If not, tomorrow evening also works at the same time. If you need more time.”
He’s one word away from practically begging on his knees, and you feel your heartstrings tug. “Yeah, tonight works if that’s okay. Is six-thirty okay?”
“Yes!” Wooyoung has no hesitation when he answers you. “Just come up whenever—you know the door code.”
“Okay, thank you again,” you say, seconds from hanging up when his voice cuts through the phone.
“YN. For what it’s worth, I’m sorry. And I’ll see you tonight.”
He ends the call before you can say anything else, and you’re left staring at the phone longingly. Yeosang’s chuckle brings you out of your thoughts. “Told you they don’t hate you,” he hums, a small smile on his lips, and you roll your eyes at him even though your heart warms.
“Should I bring a gift? Like wine or something? I don’t know…they’re feeding me. And it could be a peace offering.”
Yeosang laughs again, amused by your dilemma. “If you want to, it could be a nice gesture. But really, I think they just want to see you again.” He reaches over to you to squeeze your hand. “You guys will be just fine, okay?”
You nod, offering him your own crooked smile. “Thanks for sitting and talking, Sang. I appreciate it.” Your eyes dart to the side. “I should probably go see if I can find a proper bottle of wine, though.”
-
The bottle of wine in your hands is clutched so tightly you fear it may shatter in your sweaty grasp. You’re almost too scared to knock, but your longing to see your boyfriends (were they still your boyfriends?) overrides your fear, and you tap on the door lightly. It might be presumptuous to just walk in, even though Wooyoung told you they didn’t change the door code. You’ve done it many times before, but these circumstances are different.
Before you can chicken out and call it off, the door swings open, and San stands before you, his hair messy like it always ends when he tries to style it without help. Your fingers twitch as you keep yourself from reaching up to smooth it over. “...Hi,” you greet him instead, eyes flitting down to your hands. “I brought wine.”
“Thanks. Come on in. Wooyoung’s finishing up now.”
He steps aside, and you pass him, trying not to flinch as his comforting scent fills your brain. Oh, how you missed him and Wooyoung. The apartment is unchanged, and a picture of the three of you is still hung on the wall. “I hope you’ve been well?”
“Yea. I’ve been keeping busy.” San closes the door behind you, running a hand through his messy hair, which only serves to worsen it. “How about you?”
You shrug as casually as you can. “I’m doing well. Just been working…” There’s a long pause where neither of you knows what to do. “Do you need help with anything? Where do you want me to put the wine?”
San shrugs. “There’s not much to do. The table has already been set. Do you want to wash up or anything? I can pour the wine.”
You nod, handing over the bottle, being careful to avoid San’s touch before excusing yourself to the bathroom. You can practically hear the disappointed sigh leaving San’s mouth and you feel a sharp stab in your heart at how upset he seems to be but you remind yourself this is important. As Yeosang said, they have to be aware of what issues you’re having.
You glance at your weary face in the mirror, wiping at some smudged makeup and fixing your hair, taking any moment you can get to calm yourself down. When you can hear low murmurs in the kitchen of San and Wooyoung talking you know it’s about time for you to get out of the bathroom.
When you turn the corner into the kitchen, Wooyoung greets you with a tentative smile and a wake of his spatula. “Hey, YN. Hope you’re doing well. Are…are you hungry? It’s almost done.” Wooyoung speaks carefully like he’s triple-checking the words he wants to say before they come out of his mouth.
“Of course,” you laugh awkwardly. “Your food is always good. I hope you’re doing well too.”
It’s almost painful how tense the atmosphere is, and both you and Wooyoung cast a glance at San as if pleading silently for him to resolve it for you two. Before any of you guys can speak, the rice cooker beeps, slicing the thick stress in half and all three of you laugh. “Let’s eat,” San cheers, his eyes crinkling in the smile you missed.
The three of you move towards the seats, where three glasses of wine sit and side dishes are scattered around. Wooyoung holds the stew in his hands, setting it down in the middle of the table as you and San take your seats.
The dinner is mostly silent, aside from a couple of hums in delight at the taste of Wooyoung’s cooking. As much as you would deny it, you missed this. You missed being near them, being able to share the same space with them. As the three of you eat, you sneak glances at both San and Wooyoung. Aside from the tousled hair, San seems pretty put-together, with an easygoing smile on his face and dimples still prominent. But the dullness in his eyes is clear and he smiles and giggles way less than usual. Wooyoung’s face is lined with worry, hints of stubble peeking out, and you’re embarrassed to admit you find it attractive. His hands fiddle with his silverware as he eats, and the guilt returns to eat at your stomach.
“So…” you try and break the silence carefully, and both men’s eyes quickly focus on you. “...my brother’s boyfriend adopted a cat secretly and Hongjoong is livid, but I caught him cuddling with the cat just two days ago.”
San chuckles. “Sounds about right. Seonghwa definitely seems the type to. What, did he find the cat on the side of the road and ‘just couldn’t let it starve out there’?” You snort at San’s imitation of your brother.
“Almost spot on. It’s like Seonghwa is sitting right here, really.”
And with that, the conversation continues almost completely normally, like nothing had happened two weeks prior. Wooyoung prods at San’s cooking like always and you defend San but can’t help but throw in a jab of your own, one that San reaches over and pushes gently at your shoulder for.
At the touch, you freeze and Wooyoung’s eyes dart between the two of you. A long moment passes until you finally laugh stiffly and push him back. “What can I say? It’s true.”
Wooyoung smiles at the both of you, the corner of his lips crooked. “Good to see you take his side as always when it comes to cooking,” he teases. “Maybe I’ll make him cook next time.”
Next time. Your breath catches at those words and both San and Wooyoung take note of your hopeful reaction. “I’ll hold you to that.”
-
After dinner, all of you shuffle into the living room slowly, knowing exactly what must come. None of you want to start the conversation, but it must happen. You sit first, hands wringing in your lap. San and Wooyoung sit right next to each other, but not far from you.
“We could draw straws?” Wooyoung speaks up, his hands gripping the couch beside him. “To see who goes first.”
You don’t quite know how to react, but unlike the last time Wooyoung tried to be silly, you understand it isn’t coming from a place of malice. “I think that’s a great idea, Wooyoung,” both you and San agree, and although Wooyoung’s body tenses a tad more, his eyes soften.
“Thanks.”
With shaking hands, you hold out the straws Wooyoung had given you. Both San and Wooyoung draw, keeping their pick hidden until you pick yours. Long. San uncurls his hand and reveals his. Long.
Your gaze shifts to Wooyoung who looks just about ready to throw up at the prospect of going first. “Of course it’s me,” he laughs soullessly. “I suggested it, so I end up being first.”
“If you’re not comfortable–”
Wooyoung stops San with a quick squeeze of his hand. “No, it’s okay. I have a lot to say.” Without further ado, he turns to face you, his eyes pleading and his brows furrowed. “YN, I’m sorry. I was inconsiderate of you in the relationship, and although I meant no harm, I hurt you when I commented on ‘having more fun without you’. Although I tried to keep tension low, it only served to hurt you and I apologise for that. I should’ve been more attentive to you and considered how you may have felt when San and I went off to do our own thing without you.”
You feel a wave of relief wash over you, your heart warming at his heartfelt apology. “I really appreciate that, Wooyoung,” you hum. “I missed you a lot, and after a couple days of cooling down, I realised you meant no harm, and I could’ve told you how I felt about that with more maturity. I…I hope you don’t mind if I go next.”
San waves his hand, gesturing for you to go on. “Of course,” he agrees readily, squeezing Wooyoung’s hand gently.
“I’m sure my…complaints…about our dynamic were pretty clear. I felt left out, excluded, and separated from the two of you. And what I was feeling was valid, but my reaction wasn’t. I am sorry about how I went about talking to you guys. I assumed you wouldn’t care, and so I kept it to myself and let it boil over. And just running out on you guys was unfair of me. I didn’t explain, nor give you guys a chance to explain.”
San nods empathetically. “I was indeed hurt by your immediate assumption that we wouldn’t care. I thought it was clear we care about you—I mean, we did watch that show together and we asked if you wanted to join us next time. If you were really feeling hurt, I do wish you brought it up sooner.”
You sigh, looking down at your twisting hands, bringing one of them up to your mouth to chew lightly on the nail. “Like I said way back, I was insecure about the two of you changing your relationship dynamic just because I wanted it. Maybe it was stupid, I don’t know, but the hurt I felt wasn’t stupid. Sure, we watched the show, and sure, you asked me if I wanted to join next time. But that was it! I was an afterthought. You dismissed me when I said I wanted to join, and yet you asked me why I didn’t bring it up before?”
Before you can sink your teeth any further into your nail, Wooyoung leans forward, gently pulling your hand away from your mouth and bringing it to his lap. “Don’t bite your nails, YN. I’m sure San didn’t mean to be dismissive,” he pleads, elbowing San lightly in the ribs, who winces and nods sincerely. “I’m sure you understand, we were just hurt you didn’t trust us enough, although your reasons are understandable. We want to make things right, though, and we want you to be comfortable to talk to us about your insecurities and worries.”
“Yeah, I didn’t mean to be so defensive,” San concedes. “I got too caught up in wanting everyone to get along, I got ahead of myself. I pride myself on being the calm one, but I was too passive and that quickly turned into self-righteousness.” His hand moves to rest atop yours and Wooyoung’s, his thumb gently rubbing circles into the soft skin.
“We still want you with us, YN,” Wooyoung cuts in, “and we want to change for you. We talked about this when you were gone, and we’ll respect your decision to leave if you so wish, but we really would like to try and work this through.”
You pause for a moment. You could walk away right now, minimizing any potential hurt that could follow. But as your eyes land on your conjoined hands, any minute wish to leave is immediately squashed and you smile up at the two of them. “I want to stay too.”
San matches your smile and Wooyoung’s grip on your hand tightens almost imperceptibly. Before anything else happens, he pulls you forward, wrapping his other arm around your shoulders as he engulfs you in a warm hug. Without hesitation, San quickly joins, pressing a kiss to the top of both your and Wooyoung’s head.
As they murmur promises of how they can include you more, as well as soft ‘I love you’s in your ear, you can’t help but relax at their showcase of love. Things will turn out all right.
