Runa Ookamigawa is the beautiful and perfect student council president, but her fierce temper when angered has earned her the nickname Wolf-senpai from her frivolous and seemingly incompetent vice president, Yuuga Tsukiyama. The two are polar opposites and do not get along. However, both harbor secret sides. Tsukiyama, beneath his lazy facade, is a responsible eldest brother raising three younger sisters while their single mother is absent, and he works as a tutor to support them. When he arrives at Runa's apartment for a tutoring job, he discovers her hidden true nature: she is not effortlessly perfect but rather clumsy, disorganized, and only maintains her flawless image through immense, often tearful, effort. Mistaking him for a university student named Kiriyama, Runa does not recognize him. Tsukiyama chooses to keep his identity hidden, tutoring her as Kiriyama. As he helps her with her studies and daily life, Runa develops feelings for Kiriyama, while Tsukiyama, seeing the real Runa, falls for her himself. Their relationship becomes a tangled web of misunderstandings, with Runa unaware that the boy she dislikes at school is the same person she is falling for at home. The story also follows a cast of classmates and friends, each carrying their own hidden selves, including the observant Karasuma Ayaka and Tsukiyama's childhood friend Seto Asahi, as they navigate overlapping crushes and secrets. The narrative advances through school events like the cultural festival, where feelings are tested, and personal crises such as Tsukiyama’s mother’s sudden hospitalization, forcing the characters to confront their true emotions and decide whether to reveal their authentic selves to the ones they love.
