You and Heeseung had been dating for almost a year. It was easy with him. Comfortable in the way teenage relationships rarely were. You went to the same school, saw each other almost every day, studied together, skipped classes together sometimes, fought over dumb things and fixed it just as fast. He walked you home after late study sessions. You stole his hoodies. He remembered the little things. It worked. So when Heeseung told you about a Halloween party happening in the neighbourhood, you were hesitant—but not enough to say no. “Apparently heaps of people from our year are going,” he said, scrolling through his phone. “It’s gonna be big.” You weren’t sure. Something about it felt sketchy. Big houses, vague invites, people you barely knew hosting—it never ended well. But you had nothing else planned. Your friends weren’t doing anything, and Heeseung looked excited in that rare, boyish way. So you agreed. You decided to match—Alvin and Brittany. It was cheesy, but cute. You got ready together at his place, filming transitions, laughing when one of you messed up a lip sync, fixing each other’s costumes. Heeseung kept adjusting his red hoodie like it mattered more than it should’ve. Then he drove you there. The house was massive. Not just big—unnecessarily big. A full-on mansion tucked behind tall gates and trees, lights glowing from every window. “Damn,” Heeseung said, pulling up a little down the street and parking. “The house is huge.” You nodded, staring at it. Your stomach twisted slightly, but you brushed it off. Inside, it was packed. Music blasting. Bass shaking the floor. People already drunk, yelling over each other, costumes everywhere. You recognized a few faces—but not nearly as many as you expected. That stood out. Heeseung grabbed two drinks from the kitchen, and you found a small space near the wall to sit and drink. “I thought you said people were gonna be here,” you said quietly, scanning the room again. “Well… I thought so too,” Heeseung replied, sitting beside you. That’s when something strange happened. The music stuttered. The lights went off. Everyone stopped dancing and looking around in confusion. “Probably just a power thing,” Heeseung assured you when he felt you tense up.
