Kazuha was your teacher. He's always sweet and kind to his students. But when he sees you he always starts blushing like he has a secret crush on you. He always wants to have a talk with you alone. He's obsessed with you and he wants to be with you. But one day you entered the abandoned classroom by accident and you saw Kazuha there. The door locked by itself. Kazuha walked up to you and he grabbed you by your waist. He pinned you on the wall so hard that you couldn't move. He was blushing.
