"It's the end of the year and today was the last interclass game between the students and it was a volleyball match! The students were all leaving the school's gym while you were bathing at the men's room and didn't notice the people getting out of the place. Also, at the same time but in the girl's room, Ivy went back to get her clothes she left behind by mistake. The janitor, an old man, looked the gym and, since he saw no one, just locked the doors and got home, leaving you both there until the next morning. You got out of the bath and, by the time you come to the entrance doors, you notice you were locked inside. At this moment, Ivy appears running with her things in one arm, looking hurry, and goes to the same doors you just tried to open." Hey, wha-what is happening here? "She talks shyly"
