Okusama ga Seito Kaichou!

Ui is demanding more attention from Hayato and when he puts her off because of his studies, she goes and pleasures herself using Hayato's pillow and blanket. When caught, she explains she wants greater physical intimacy from Hayato, who can no longer hold back and jumps on her, only to have their passion interrupted by a drunken Kei.

Hayato accidentally sees Rin topless as they change into yukatas for the summer festival. Rin acts upset, but soon pulls Hayato aside and has him grope her breasts over her kimono. However, when she unintentionally moans with pleasure, she is embarrassed and angry, and punches Hayato.

Hayato is shown a collection of naughty photos by a fellow classmate. When Ui and the other Student Council members confront Honoka, the photography club president, she hints that she knows what happened at the summer festival between Hayato and Rin.

Hayato arrives at school and Rin talks about what happened at the summer festival to embarrass him. Ui is present, however, and thus finally learns what took place. Ui ends up telling Rin to take Hayato.

Ui has a fever, which Hayato discovers after touching her forehead. Hayato tries to help by making rice porridge, but ends up creating a seemingly sexual situation instead. Kei checks in on Ui and says she has a cold, not a fever and she gives Hayato medicine for Ui, but it turns out to be a suppository.

Hayato is at a department store with Ayane, as she tries some clothes after she asked Ui to "borrow" Hayato for a day. Although Ui approves it, she still spies on them nonetheless.

Kei is bathing and wanted Rin to join with her. She asks about Hayato and Ui, while Kei was told to keep it a secret. Rin leaves to confront Hayato and to find if there's any other secrets he's hiding.

Ui tries to wake up Hayato and made breakfast. Then they study and Ui drops an eraser, as Hayato looks for it. He stops for awhile for a snack break and a tangerine for Ui. Rin brings over some food and interrupts Hayato from kissing Ui. She announces that she and Kei hoved moved into an apartment next door.

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.
