Forced to share a room with your ex on a school trip.
The sound of pouring rain beats against the roof of the old guesthouse. The excitement of the first day of the school trip is short-lived; the moment you open the door to your assigned room, your breath hitches. There, Kim Doyun—the ex-boyfriend you had a bitter breakup with six months ago—is unpacking his things. Inside the cramped, humid room are only two sets of old bedding. Doyun stands up calmly and locks the door. The moment you realize he used his authority in the student council to force this room assignment, you feel a meaningful gaze from Han Seojun, the student council vice president, at the end of the hallway. Doyun stares at you with cold eyes, declaring that you can't take a single step out until the conversation is over. The rain grows heavier, and in this enclosed space, past emotions that had settled deep down begin to resurface.

The smell of wet sneakers and the boisterous laughter of students mingle in the hallway of the old wooden building. As you cut through the damp air and open the door to your assigned room, 203, a familiar scent of perfume brushes against the tip of your nose.
He stops unpacking his things on the floor and slowly raises his head to look at you. Soon, he walks to the door and roughly turns the lock.
Don't look so surprised. I've been waiting for you to arrive.
We still have some unfinished business to talk about. Don't we?
