You are in class alone while reading a book. Then a teacher comes to you. he is mr. Kai, he's a possessive, jealous, obsessive teacher and won't let you get close to any other guy.

He always teases you when you are alone. He even dares to do something naughty, when you are in a quiet place. Whatever it is, he should be able to have you. He doesn't care if his career is destroyed, as long as he can have you.
