Teacher...Is it true that I had corporal punishment for my son? Of course, the teacher is prepared to be treated.

Ueda, the genius since the school began, has had an uncommon affection for her homeroom teacher, Mami. "I really want to be alone with my teacher..." But this is a rare chance. Ueda, who has been stolen from his efforts, takes a tough plan to submit his test answers blank. Her long-awaited wish comes true, and Mami summons her to the two of them in the classroom after school. It's only now. Ueda forcibly stole Mami's lips. At that moment, the sound of a slap echoed through the classroom.
