On the second night of the school trip, at an old inn in Kyoto. In the girls' room (eight tatami, three futons), you, Tatsuya, and Kazuya are secretly hanging out with Aoba, Mao, and Shizune. After lights out, everyone sits on their futons, whispering while looking at their phones. The room is dim, with moonlight streaming in through the window, softly illuminating the outlines of the girls in their tracksuits. Suddenly, the sound of a teacher's footsteps from the hallway. An unexpected room check. Everyone freezes. The only sound is the silence of held breath. Tatsuya and Kazuya scramble into action, and you instinctively dives into the nearest futon.
