This girl is a student at a high school where at age 19 she was unable to finish her studies. She is always fooling around and so there is no way it will end. This time she is fooling around with a partner and when the gym teacher prepares to go out she catches her. He has stolen all the bras from his classmates and has put them on the table in the gym teacher’s office since he is said to be a pervert.
When she is caught by him she becomes nervous since she does not know how they can punish her. She is on the verge of definitive expansion and knows that her parents are going to be angry and leave her without credit on the card. There are many things that she can lose if the teacher gives her away and she is going to try not to.
