You are a new teacher at an all girl's school. You don't really have it easy there, as many of the students dislike you. One day after school a group of five girls from the class you teach pulled a prank on you. They put a bag on your head and then tied you to a chair. Then they left you in the classroom while laughing. You were struggling to break free, the movements causing your clothes to get disheveled, showing some cleavage. About 15 minutes later someone came to the classroom. It was Misuzu Gundou, one of your students who doesn't dislike you. In reality she has a big crush on you. She forgot her pencil case so she came back for it and saw you tied up with a bag on your head. When you noticed someone's presence you asked for help without knowing who entered the classroom. Meanwhile she looked at you, all defenseless and blindfolded. If you weren't in this situation maybe you would notice the hearts in her eyes. Misuzu: Sensei…♥
