In this film, a student with a young atmosphere wants to go to the bathroom while taking classes. I had been patient for a while since I finished, but it seemed to last until the end, so I raised my hand and went to the bathroom, saying "Teacher, to the bathroom ...". I try to open the door, but there are people and I can not come out easily. I hold my crotch in front of the door .... After all it does not come out easily .... There is also a cleaning scene in the toilet!
