The night breeze sent shivers down your spine. For a summer night, it was entirely too windy.
You drew closer to your friend as you moved down the street. Everything was pitch-black, forcing you to navigate more by intuition than by actually knowing where you were headed. The chirping of crickets and the hooting of owls kept your footsteps drowned out.
“I thought this would be funny, but it’s starting to freak me out,” your friend whispered, gripping your arm a little tighter.
“Don’t say that. We’re already here, we’re seeing this through,” you replied without paying her much attention. Your entire focus was locked onto the figure walking a few yards ahead of you.
Tension weighed heavily on your shoulders. You weren't out here for simple fun or curiosity like Fang was; you were furious. Just this afternoon, you had spotted Seonghyeon leaving your stepfather's study, when he was supposed to be tending to the garden, and right after that, your stepfather had thrown an absolute fit upon discovering someone had bypassed security to steal a master keycard.
Knowing that your former best friend had turned into a petty thief, and that he had essentially stolen from you, burned deep in your chest.
“But what if this ends badly?” Fang asked, her brow furrowing comically. “I'm still grounded for what happened two weeks ago.”
“Aren’t you the one who always says you have to take risks and live life to the fullest? Take your own advice.”
“Oh, sure, but if we end up six feet under, I don’t know how much living we’re going to get to do.”
“Don’t talk like that. Hyeon crossed the line this time, and I’m going to make him give back what he stole before my stepfather calls the cops,” you said, your voice steady and resolute. Without realizing it, Fang shot you a knowing look out of the corner of her eye.
“You still call him Hyeon.”
“What?” you asked distractedly, trying to keep your pace and not lose sight of the guy you were tailing.
“You’re still calling him by his nickname, not his actual name. Like you are still friends.”
That made you stop dead in your tracks. You stared at her flatly for a few seconds.
“Habit.” You rolled your eyes and kept walking.
“Yeah, right. Habit,” Fang replied with a small smile, the tension visibly draining from her shoulders. You ignored her.
Seonghyeon abruptly stopped walking and snapped his head back toward your direction.
“Shit,” you hissed, grabbing Fang by the arm and dragging her down into a nearby bush to hide from him.
After a few seconds, both of you peeked out to see where he had gone, but there was no sign of him.
“What? Did he vanish?” Fang asked, looking every which way.
“Do you think he saw us?” you asked with a frown, staring at the exact spot where you had seen him last.
“Well, I hope not, because I didn't spend the last ten minutes freezing my butt off for nothing,” she grumbled.
There were a few different directions he could have taken, but something inside told you he had chosen the narrow path between two rows of trees a few yards to your left. Trusting nothing but your gut, you stood up from behind the bush and headed that way.
Fang hurried after you a few seconds later, quickly gluing herself to your side again the moment she caught up.
“Can you remind me why we are stalking your ex-best friend into the middle of nowhere in the dead of night?”
“I already told you. He stole from my stepfather. He snuck into his study and took the security keycard.”
“Oh, but didn’t you say earlier that he wasn’t capable of doing something like that?”
“Not on his own, but maybe the guys convinced him. You know how the Pogues are.” The moment the words left your mouth, you regretted them. Who were you to say something like that? After all, you were born a Pogue too. You realized with a sinking feeling how much easier it was getting for you to throw around comments like that in front of other Kooks. Every day, you were becoming more like them. A bittersweet ache squeezed your stomach.
“Yeah,” Fang said quietly. You couldn't quite read the hesitation in her voice.
Once the trees cleared from the path, you finally saw where Seonghyeon had been heading.
Standing before you was a massive house, abandoned for decades. Years ago, teenagers used to throw parties here, until a girl died one night and someone made up a rumor that the house was cursed. Everyone said it was stupid, but the parties stopped anyway.
Your stepfather had bought it a few years ago, for reasons unknown. And he'd made sure everyone knew it was his property and didn't set foot there.
What was Seonghyeon doing inside with your stepfather’s keycard? What did Seonghyeon want from that house? Your initial anger began to blend with a heavy dose of intrigue. Adrenaline spiked through your veins, nearly making you smile.
“Where the hell are you going?” Fang whispered, watching you step forward.
“Where do you think?” you shot back rhetorically, never breaking your stride.
You heard Fang mutter something unintelligible under her breath before following you. “Just so you know, if we die, I am haunting you in the afterlife.”
“Nobody is going to die, drop it already,” you replied, rolling your eyes.
The front door was left ajar. You slipped inside silently, trying not to budge the frame so it wouldn’t make a sound. Inside, everything was pitch-black and practically dead silent. You instantly ruled out the idea of this being the first party the place had seen in ages.
You gestured for Fang to halt and listened intently to your surroundings. To anyone not paying close attention, the house would seem completely vacant. But if you focused hard enough, you could hear several voices murmuring from the second floor.
“Come on.” You signaled Fang to follow and crept up the nearest set of stairs, keeping your movements as quiet as humanly possible.
At the end of the hallway, a dim, warm light filtered through a cracked door. You and Fang exchanged a hesitant look, but the uncertainty didn’t make you back down, if anything, it only fueled your desire to keep going.
Standing right outside the room, you peeked cautiously past the doorframe to see what was happening inside. To your right, Fang did the exact same thing, her curiosity finally overriding her fear.
And there they all were. Martin, Juhoon, James, Keonho, and, just as you had guessed, Seonghyeon.
The five of them were gathered around a table in the center of the room. Martin held a small flashlight that offered nothing more than a faint yellowish glow. In the center of the table sat an old, scuffed leather briefcase. Seonghyeon had just pressed a hidden latch on the side, causing the false bottom of the briefcase to snap open with a sharp click.
Inside lay stacks of old bearer bonds and a dusty cassette tape.
“I told you guys it was in here,” Keonho said, pointing at the briefcase. None of them had noticed your presence.
“Holy shit,” James muttered, sounding completely floored.
“So this is it, right? We found it. We found the treasure. We know where it is, and now we just have to go get it,” Martin said, getting more excited with every word that flew out of his mouth as he ran his fingers over the bonds.
Treasure? Bonds? What on earth was all of this?
You and Fang looked at each other, utterly bewildered and shocked. What were they even talking about? Your mind raced at a thousand miles an hour, trying to connect the robbery at your house to that briefcase.
“It can’t be this easy,” Juhoon added, sounding as level-headed as ever.
“Exactly,” Seonghyeon agreed, carefully sliding your stepfather's security keycard into his pocket. “It makes zero sense that a bunch of loser teens found the map to a treasure people have been hunting for decades. Lucky for us, we managed to kill the property sensors with this.”
You gritted your teeth at the sight. The idiot really had done it.
“Are they talking about a real treasure?” Fang whispered to you. You simply pressed your index finger to your lips to keep her quiet, your eyes glued to the conversation.
“First of all, speak for yourself on the ‘loser teen’ part,” Martin started. “Second of all, maybe it’s just destiny wanting us to be the ones who find it. We’re just built different.” He shrugged.
“Are you high?” Juhoon asked, completely deadpan.
“I literally told you no earlier!”
“Well, you sure sound like it,” Seonghyeon chimed in.
“You guys and your pessimism. Can't you just accept that something is finally going our way for once? Just rela…” Martin didn't get to finish his sentence because James abruptly cut him off.
“Wait. Do you hear that?”
Everyone went dead silent, and you and Fang strained your ears to listen too.
“Is that a car?” Keonho asked, confused.
Seconds later, the five of them rushed to the window on the far side of the room to see where the noise was coming from. From your vantage point, you couldn’t see what was happening outside.
“Do you think someone else came here?” you whispered to Fang.
“At this point, I don’t even know what to believe,” she replied, shaking her head.
“Holy crap. That’s a lot of guys,” Keonho exclaimed, backing away from the window.
“Shit, and they have bats,” James added.
“Is that a fucking gun?” Martin asked, alarmed as he watched one of the men climbing out of the van tuck a pistol into the waistband of his pants.
“Don’t tell me they’re here for us,” Juhoon said, his voice losing its calm demeanor entirely. Those men didn't look like town security, they looked far more dangerous and ruthless.
“Let’s not stick around to find out. We’re leaving now,” Seonghyeon told them, snatching the cassette off the table as he turned toward the door.
The movement was so sudden that neither of you had time to hide. Turning around, Seonghyeon didn't take more than two steps before locking eyes with both of you standing there. He froze instantly, his eyes widening. The other four quickly followed his gaze until they saw the exact same thing, shock washing over their faces.
“What the hell?” Keonho managed to gasp out before the sound of the front door downstairs being violently kicked open echoed through the house.
“Search everywhere and find them!” an unfamiliar voice barked from below, followed by the heavy thud of multiple footsteps scattering in different directions.
“Fuck,” Seonghyeon cursed. Reacting fast, he shoved the cassette into his back pocket. He grabbed the leather briefcase with one hand, but before he could secure the bonds, heavy footsteps began frantically mounting the stairs. They were trapped.
“Out the window, now!” Juhoon yelled.
Seonghyeon looked at you, processing your presence in a split second of pure panic. Forgetting all hostility, he grabbed you tightly by the arm.
“Move!” he dragged you with him toward the upper-floor emergency exit, an old iron fire escape that led down into the back alley. The rest of the guys and Fang scrambled right behind you.
Martin was bringing up the rear, clutching the briefcase to his chest. But as he stepped over the window frame onto the metal grating, the old leather handle snapped. The briefcase slammed onto the floorboards inside, scattering half the bonds across the room. Martin lunged down to grab it, but a gunshot shattered the wooden frame, sending splinters flying.
“Leave it, Martin! Move!” Seonghyeon roared from the fire escape, pulling you down.
With his heart in his throat, Martin had to abandon the briefcase and the bonds on the floor of the mansion to save his skin, leaping onto the metal structure just in time.
You all flew down the iron stairs at breakneck speed, and the moment your feet hit the pavement, you bolted toward the alley exit.
“Hey, there they go!” one of the men shouted from the upstairs window.
Within seconds of clearing the house, you had several men pursuing you on foot. Everyone kicked into overdrive. Seonghyeon still maintained a tight grip on your arm as you ran, guiding you through the thick brush.
“Fuck, fuck, fuck,” Martin cried out when he glanced back momentarily and saw how close they were on your heels.
“Where are we going?” Fang yelled, breathless as she ran.
“We need to find Godzilla!” Keonho shouted back.
“Who?” Fang asked, even more confused.
“It’s Martin’s van.” James clarified.
“Hey, what’s your problem with my Godzilla?” Martin snapped at Fang, never slowing his pace.
Despite the life-threatening situation you were in, you couldn't help but feel a jolt of surprise at what you had just heard. Ever since he was a kid, Martin used to say he would name his first car “Godzilla” because, according to him, it sounded “intimidating.” In reality, he had ended up inheriting his aunt's ancient, bright yellow, completely beat-up van. It was the least intimidating thing on wheels, but it ran, and that was enough for Martin.
It twinged with a bit of pain to realize you still remembered those little details about the boys. The nostalgia was short-lived, though, as reality slammed back into you: you were running for your life alongside the person who had just robbed your own home.
You spotted the yellow van a few yards ahead and nearly gasped in relief. Unfortunately, those men weren't about to let you go that easily.
The loud crack of another gunshot echoed down the street. Seonghyeon forcefully shoved you to the ground, ducking down right beside you to dodge the bullet.
“Holy shit, that almost hit me,” you heard James say, panicked, from his spot on the asphalt.
“We need to get out of here right now!” Martin yelled, sprinting the final stretch to the van.
Seonghyeon hoisted you back up and dragged you to the vehicle. You turned around to grab Fang, but saw she was already being hauled along by Keonho. Martin threw himself into the driver's seat with Juhoon riding shotgun, leaving the rest of you to pile into the back.
Seonghyeon yanked the back doors open and gave you a gentle push inside.
Once the others scrambled in, Seonghyeon climbed in last and went to slam the doors shut when a hand violently clamped down on the edge, stopping him.
“You kids aren't getting away,” one of the strangers snarled, grabbing Seonghyeon by the arm and trying to pull him out of the van by brute force.
“Martin, drive!” you screamed before throwing yourself toward your ex-best friend to help him break free. You planted a hard kick right into the man’s stomach. As the guy keeled over and his grip on Seonghyeon loosened, James delivered a brutal shove that sent him crashing to the ground.
Martin floored the gas pedal, causing all of you to go flying in different directions across the floor of the van.
“Fuck, a warning would have been nice,” Fang groaned, bumping her head against one of the side windows.
As you scrambled to sit up, you moved to secure the door that hadn't been fully shut, but another hand jammed into the gap, preventing it from locking. The stranger didn't get to do anything else because you yanked the door open a fraction of an inch to catch momentum and slammed it shut with all your might right onto his fingers. A sharp howl of agony echoed over the engine as the blow landed. You cracked the door open just enough for him to rip his hand back, and the second he did, you slammed it shut for good.
You slid down to the floor, leaning your back against the metal doors as your lungs burned for air.
For a solid minute, the only sound was the collective gasping of everyone trying to catch their breath as Martin drove, gradually easing off the gas the further away you got.
“What the hell was that?” Juhoon asked, visibly shaken, breaking the silence. Nobody knew how to answer.
“What were you two even doing there?” Seonghyeon demanded, fixing his sharp gaze entirely on you.
Your panic instantly melted into a cold, hard fury. “What was I doing there? I was following you, you petty thief!” you snapped, pointing a finger directly at him. “I know exactly what you did this afternoon. You snuck into my house and stole my stepfather’s security keycard. That’s why we were there! I came to get back what you took!”
The boys froze. Seonghyeon’s jaw clenched, but he didn't break eye contact.
“You don’t know what you’re talking about,” he said, his voice dangerously low.
“Oh, really? Then whose keycard did you use to get into that house? And what about those men with guns who almost killed us? You've dragged me and Fang into a monumental mess!” Your voice practically vibrated with immense annoyance.
Seonghyeon crossed his arms, retreating into a stony silence. The others exchanged uncomfortable glances, but nobody said another word until Martin finally killed the engine.
You looked out the window and realized you were parked in his yard, deep on the Pogue side of town. It had been years since you last stepped foot in this neighborhood. His house looked exactly the same, save for the fact that it was in slightly worse condition than the last time you'd been there.
“Are you seriously bringing them here?” Seonghyeon asked incredulously, glaring at Martin.
“Where else was I supposed to take them? We’re all losing our minds right now, we need to talk things through,” Martin replied, pulling the key from the ignition.
“There is nothing to talk about with them. They need to go,” Seonghyeon said flatly.
“We’re right here, you know,” you reminded him, indignation rising hot in your throat. “And I am not going anywhere until you hand over my stepfather’s keycard and explain to me what the hell that cassette tape was.”
Seonghyeon whipped around to face you, his eyes practically throwing sparks.
“You want me to say it to your face? Get out of my sight. Leave.”
Fang gasped, stunned by his sheer rudeness. You held his gaze, your expression hard and unyielding, completely refusing to back down.
“Seonghyeon, drop it,” Keonho warned, trying to keep the situation from imploding.
Seonghyeon rolled his eyes, threw the van door open, and stormed out toward the house. James and Juhoon lost no time following him inside.
Martin let out a heavy sigh from the front seat.
“Come on, girls, come inside.”
The four of you left in the vehicle piled out at a much slower pace. Fang absolutely hated how awkward the situation was, but she could see you were dead-set on getting to the bottom of this, so she kept her mouth shut and stuck by your side.
Inside, Martin’s house was dark save for a single small lamp that cast a faint, warm glow. It was just as you remembered it, only considerably messier, if that was even possible.
Fang and you stood out like sore thumbs. Your expensive designer tops and trendy sandals didn't fit the house, nor did they fit the boys' worn-out clothes. You were two entirely different worlds, and you noticed you weren't the only one who realized it.
Seonghyeon sank into the couch, throwing his head back and closing his eyes in sheer frustration. Keonho wandered into the kitchen to fix himself a sandwich, the stress of the evening apparently having worked up his appetite. Juhoon sat down right next to Seonghyeon, while Martin claimed the armchair off to the side.
James pulled a Coke out of the fridge.
“Anyone want something to drink?”
“Toss me that open Monster in the back,” Martin called out.
“Damn, how long has that even been sitting in there?” Juhoon asked with a disgusted face.
“Don’t know, don’t care,” the blonde replied lightheartedly.
James turned toward where the two of you were standing.
You shook your head. Fang, on the other hand, had a throat as dry as sandpaper from the scare.
James filled a glass with tap water and set it on the dining table for her to grab.
“Is it from the tap?” Fang asked, her expression twisting slightly with distaste.
“Excuse me, Your Majesty, but we don’t exactly have the cash to buy bottled supermarket water twenty-four-seven out here. Besides, it’s perfectly potable,” Seonghyeon shot back, mocking her with distinct bitterness.
“Leave her alone, she just asked a question. Calm the hell down for once,” you said, rolling your eyes.
He glared daggers at you.
“Don’t tell me what to do.”
Before the two of you could launch into another full-blown argument, Martin cut in.
“Can you guys cut it out? Both of you.” He looked at you both to make sure you were listening. “We need to talk about what happened.”
“Fine,” you said, crossing your arms. “Start by explaining what that briefcase was doing in the abandoned mansion, and why those armed lunatics were hunting us down.”
“Our plan went completely to shit anyway, so it doesn’t even matter,” Juhoon sighed from the couch. “Those guys probably ran off with the briefcase and the rest of the bonds. We walked away with nothing.”
“Not entirely,” Seonghyeon intervened. With a slow, deliberate movement, he reached into his back pocket and pulled out the old cassette tape, placing it on the coffee table right under the dim glow of the lamp. “We have this.”
Everyone stared at the small plastic object. The silence in the room grew heavy.
“What is that tape even of?” Fang asked, taking a step forward, incredulity written all over her face. “And what is this about a treasure?”
Martin looked over at Seonghyeon, silently asking for permission to speak. Seeing the dark-haired boy simply avert his eyes in annoyance, Martin took a breath and leaned forward in his seat.
“That house used to belong to an old investor who vanished mysteriously back in the eighties. We found a lead saying that before he disappeared, he hid his fortune somewhere on the island, and the maps for the coordinates were hidden in a false bottom of his briefcase inside the mansion. To get inside without setting off the alarms, we needed the master keycard your stepfather's construction company bought up. That's why Seonghyeon took it.”
You froze. Your anger ebbed away by a fraction of a millimeter, instantly replaced by a cold spike of confusion.
“And the men who attacked us?” you asked. “They had guns. They weren't cops, and they definitely weren't my stepfather's security guards.”
“They weren't,” Juhoon affirmed, his tone deadly serious. “They’re dangerous guys. They've been poking around the Pogue side of town for weeks, looking for the exact same thing we are.”
James walked over to an old radio cassette player Martin kept on a shelf, blew a layer of dust off the machine, and popped the deck open.
“Only one way to find out what kind of cards this tape is holding,” he said.
Seonghyeon reached out, grabbed the cassette from the table, and handed it over to James. His eyes locked with yours for a split second, there was a heavy mix of resentment there, but also a strange shadow of warning in his gaze that sent a shiver straight down your spine.
James slid the tape in and hit Play. The machine emitted a harsh static hiss for a few agonizing seconds, a wall of white noise that filled the cluttered living room. Suddenly, a voice warped by time and degraded magnetic tape began to speak. It was the voice of an older man, breathless and trembling.
“If anyone is listening to this... it means it's already too late for me. They're coming for the money. Do not trust the county authorities, they're all bought and paid for. All the money from the commercial fund was funneled into shell accounts before they cordoned off my properties...”
The man on the recording coughed violently, and in the background, you could hear the distinct, roaring crash of the ocean waves and the wind.
“I made a deal to hide the promissory notes and the vault map down in the coastal tunnels, but they crossed me. The young lawyer handling my finances... he knows everything. He orchestrated my disappearance to seize the land. His name is...”
The tape emitted a violent, loud crackle of static, stretching the man's voice until it became entirely garbled for a few seconds due to the worn-out magnetic strip. You leaned forward, holding your breath, your heart hammering against your ribs. The boys barely even blinked.
After a few agonizing moments of pure distortion, the voice subtly cleared up right before cutting out completely:
“...Jeong. Do not let the Jeong family get their hands on...”
The cassette gave a sharp click and stopped. The silence that fell over Martin’s living room was absolute.
You felt the ground vanish beneath your feet. Fang turned to look at you slowly, her eyes wide as saucers, her mouth hanging open.
Jeong. That was your stepfather's surname. The man who had married your mother three years ago, the wildly successful businessman who had purchased the land encompassing the abandoned mansion, and who seemed so pristine and respectable in the eyes of the island's entire upper class.
“No way,” Fang whispered in a tiny thread of a voice. “Your stepfather... your stepfather is mixed up in this?”
You looked at Seonghyeon. He didn't look surprised at all, on the contrary, he was staring straight at you with a hard, almost pitiful expression, confirming that he had already suspected something before he ever stole that card.
“The name Jeong is common,” Juhoon offered, though his voice lacked any real conviction. “It could be any other lawyer from back then. Your stepfather was incredibly young in the eighties.”
“That would explain a lot of things,” Keonho muttered from the kitchen, leaving his half-eaten sandwich on the counter. “The whole town wondered why your stepfather's construction company would waste money buying that rotting old mansion just to keep it chained up and locked down. It’s not garbage to him, he bought it to make sure nobody ever poked their noses inside.”
“We still don’t know if it’s him a hundred percent,” Martin interjected, staring at the radio with a mix of excitement and dread. “The tape is messed up right at that part. But if your stepfather is tied to this... it means the guys shooting at us tonight might be connected to him. Or to his enemies.”
You stood paralyzed in the middle of the room, staring at the cassette tape resting inside the player. Every reminder of your luxurious life on the Kook side of town, the elegant dinners, the false security of your new house, crumbled in an instant. If that tape was telling the truth, your stepfather was hiding a very dark, criminal past. And worst of all, you were trapped on the wrong side.
Seonghyeon rose slowly from the couch, walking over until he stood right in front of you. He looked you dead in the eye, a coldness in his gaze that chilled you to the bone.
“I told you,” he whispered, his voice incredibly raspy. “Your new family is hiding a hell of a lot more crap than you think. So you better decide right now what you're gonna do, kook. Because we aren't stopping until we find that treasure.”
