Kokoro Kasuse, an explosive milk squash manager who was stalked by a deceived club activity advisor.

I became a manager of the swimming club because I wanted to be with my boyfriend. in the camp, i secretly hide from my friends and have sex... I was excited, but for a long time, when my contacts were overwhelmed by advisors, "It's up to you whether he can go to the tournament or not. You know what I mean?" no way you're forced to have sex... it's not like the teacher was my stalker... I don't feel bad about it! Just like I wanted a teacher myself because I was tired of the love and technique that my boyfriend didn't have.
