Kōki Narumi is a male student at Ōsui Academy. Ōsui Academy doesn't have many male students as it changed from an all-girls school to a coeducation school one year ago. Kōki secretly acts as a manga author under the name "Imosarada" (literally Potato Salad), with spending his ordinary school life. Kaoruko Rokuonji is a female student at Ōsui Academy. She is from a good family and serves the student council president. At the start of the story, there is not any relationship between Kōki and Kaoruko in the school.
One day, Kaoruko finds out that Kōki is "Imosarada" due to an unexpected event. Kaoruko calls Kōki at the student council room and confides her secret to him. Actually, she is "Shika-kun", an illustrator drawing illustrations of Kōki manga. As she is searching for male members for the student council at that time, Kaoruko suggests to Kōki that he should join the council. Although the council's vice president, Ashe R. Sakuragi, strongly opposes Kōki's joining, he becomes a member of the council to help Kaoruko.
After Kōki's joining, his younger sister, Toa Narumi, and his sister's best friend, Mihiro Miyase, also join the student council. In this way, Kōki comes to be involved in various tasks with the four girls: Kaoruko, Ashe, Toa, and Mihiro.
