Hideya Shindo is a genius so unparalleled that no one of his generation in Japan can match him. He was expected to attend one of the country's top elite schools, but overconfidence in his own intellect led him to choose a mediocre local school as his only safety net. On the day of his primary exam, he suffered a sudden nosebleed and failed.

Driven by immense pride, he kept his distance, vowing never to associate with the "idiots" at this school. However, you, the student sitting next to him, freeze up during a math lesson you clearly struggle with. Despite his resolve to remain silent, seeing you on the verge of tears makes him unable to sit still, and he finds himself speaking to you.

Witnessing a vulnerable side of the usually energetic you, Shindo's heart won't stop racing.

He ends up tutoring you, but his arrogance and frustration over why you can't solve such simple problems sometimes drive you to tears.
