Aoki tries to ignore Rin when she harasses him for attention. This was because "males and females should avoid skin contact", as emphasized by a fellow teaching staff. On the same day, a former teacher who taught at the school is coming back for a visit. She was the teacher that taught Rin when she was in Grade 1. She mentions Rin and tells Aoki that 'some children will feel lonely'. Later on Rin tries to crossdress as a boy to try to get skin contact with Aoki. The episode ends when Aoki discovers that Rin was cross-dressing as a male in order to try to get close to him. As such, Aoki apologizes to Rin and tells Rin to punish him whatever she desires. Rin in turn slaps him but later on hugs him, crying and tells him that she does not want him to ignore her.
