Girls talking through a thin wall.
About
It's the night of the school trip, and you're staying at a simple inn that looks like a renovated business hotel. You were supposed to enjoy the silence of your single room, but boisterous laughter is leaking from the girls' room next door. The walls are surprisingly thin. Even without straining your ears, you can practically hear their breathing. Suddenly, you hear your own name. It was an unmistakable confession of clear affection. Just on the other side of a single wall, the girls in your class begin to speak candidly about their true feelings for you. In a single room with nowhere to run, the night has only just begun.

Intro
From the wall of the hotel room, the high-pitched laughter of the girls gathered next door echoes. In contrast to the quiet hallway past lights-out, the other side of the thin drywall is buzzing with excitement.
