My Wife is the Student Council President

During the student council election speeches, Ui Wakana promises a liberalization of love, tossing condoms to everyone and wins by a landslide, to the dismay of her opponent Hayato Izumi, who becomes her vice president in the student council. After returning from cram school, Hayato discovers Ui in his apartment. She declares that she is his wife because their parents had drunkenly arranged for them to get married when they were 3 years old.

Hayato wakes up to find Ui in his bed. He discovers the "perfect student" she presents herself as is a facade, in fact she's rather lazy, useless at chores, and can't cook.

The head of the disciplinary committee, Rin Misumi, is upset that Ui's campaign has led to more public displays of affection. Hayato tries to show her that hand holding is no big deal by shaking hands with her but this embarrasses Rin extremely. That night, Ui suggests a hand-holding experiment and tries it out on Hayato, but it leads to a more erotic situation.

Rin continues to stop hand holding and public displays of affection by students, but Ui defends their actions. After class, Rin follows Ui and Hayato. When Hayato is alone, she confronts him and the two end up sheltering at a love hotel because of the rain. At that moment, Ui sees the two of them leaving the hotel together.

Ui becomes depressed after seeing Rin and Hayato come out of a love hotel. The council listens to a very similar case during their meeting, with Rin and Hayato vigorously defending the "it was a misunderstanding" side. When they learn in a follow-up email that the couple have made up with a kiss, Ui asks for the same from Hayato afterwards.

Ui and Hayato receive a surprise visit from Ui's mother Misato, who looks more like Ui's little sister. Misato visits Hayato's apartment for dinner, and then shares an awkward bath with him. Ui later gives Hayato a back massage which leads to tickling and foreplay until Misato interrupts.

Rin and Kei Misumi move in next door to Hayato, who tries to keep his cohabitation a secret. Rin visits Hayato frequently, causing him to try to hide Ui. But Ui gets revenge for his not paying attention to her. Rin finally finds Ui's underwear and lipstick, and Hayato has to claim they are his to cover Ui, leading to a rather embarrassing misunderstanding.

As Hayato prepares for a major exam, Rin and Kei notice his bags under his eyes and take him to the nurse's office. Hayato is surprised to learn that Rin told Kei about his alleged cross-dressing secret. As Hayato sleeps, Rin and Kei dress him like a girl and argue over who's panties he should wear.

Rin gives Hayato a gift bag with panties, while petite girls Sawatari and Karen watch them. Karen tells Ui that Rin is bribing Hayato, which leads Ui into thinking whether she should reveal her relationship secret to Karen and Ayane.

While waiting by the school entrance, Hayato sees Sawatari fall down while carrying a huge backpack, and brings her to the infirmary to rest. Sawatari suspects that Hayato and Ui's relationship is more than it appears, so she follows him home. Things quickly fall apart once she is invited inside.

Sawatari returns Hayato's panties and leaves a thank-you present for him. Ui, who has turned the legal age to marry, thinks the gift is for her and puts on the nightie. At first Hayato is shocked to see her in such daring clothes, but succumbs to her foreplay.

Ui and Hayato receives another surprise visit from Misato at their apartment. This time, Ui's father Ryouji comes along to see if Hayato is suitable to be Ui's husband.

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.
