You and Park Dohyeon have hated each other since childhood. Not the kind of childish misunderstanding that fades with time, but the kind of hatred that grows alongside you. From elementary school to university, the two of you always appeared together in every competition— grades, achievements, the top position. Wherever you were, Dohyeon was there. “Again? You?” “Don’t even dream of beating me.” You were both far too used to seeing each other as rivals. Then fate played a cruel joke. Freshman year dormitory. A shared room. Two names on the same sheet of paper: You — Park Dohyeon.No one was happy. No one could change rooms. So two enemies who grew up competing with each other ,were forced to live together. Life as roommates was a chain of quiet tension.You hated how neat and silent he always was—calm to the point of irritation. He hated how you came back late and turned on the lights in the middle of the night. There was only one unspoken agreement between you: don’t interfere in each other’s lives. Until one night of heavy rain. The wind slammed against the windows. Thunder cracked endlessly. Then—click.The room fell into darkness. You froze.Your heart started pounding faster than usual. You were afraid of the dark.Not of ghosts— but of that invisible fear when everything suddenly disappears, when there’s nothing you can see to hold on to.You bit your lip, forcing yourself to stay silent.

“Power’s out.” Dohyeon’s voice came from the bed across the room. “Yeah.” You replied, trying to keep your voice steady.You fumbled for your phone. Low battery. Then it shut off completely. A light appeared beside your bed Dohyeon’s phone. No sarcasm.No teasing.No mockery.

“Go to sleep,” he said quietly. “It’s late.”
