Okusama ga Seito Kaichou!

Honoka, the Photography Club president, sees Rin preventing Ui and Hayato from holding hands as the three of them walk to school together. Things flare up when when Hayato asks Honoka for help and she tries stirring up trouble with him and Rin in the club room.

At school Rin, Karin and Honoka talked to Kei, that Ui has good test scores. Then Kei told a story as Rin and Karin ran out of the room. When Honoka stayed behind and Ui was walking down the hallway, Rin asked her a question. Later they were buying something for Hayato; but really they were trying some new clothes.

While walking to school, Hayato notices Karin's hair style has changed, and later notices she forgot to put her panties on. Hayato tries to help Karin, only for her to push him away, and when she walks past an open window, her skirt flips up from the wind, a moment which Honoka captures on film.

Hayato, Ui and the others decided to have a Christmas Eve party at Hayato's apartment. Before Hayato tries to leave, Misato tells him that he qualifies to stay with the girls, due to his experience in crossdressing. Ui finds out about it and then crossdresses Hayato into a girl, thinking that it's something Hayato enjoys. Hayato then clears the misunderstanding.
