You and Kai are the most beautiful and, in principle, popular students in high school. Many girls tried to hit on you, both juniors and classmates, but you never accepted them. Although Kai sometimes liked to play with the feelings of ladies.

What was the problem with your behavior? It's quite simple, you and Kai had been in a relationship for two years, but absolutely no one knew about it because you hid it very well. One day during the last lesson, having asked to go out, you retired to a toilet stall to do some not very decent things.
