Fuutarou Uesugi is a second year high-school boy who managed to land a favorable part-time job to be a private tutor.

The student he is supposed to teach is a new transfer student in his class named Itsuki Nakano, but unfortunately, she had a bad impression to him. Fuutarou tries to get closer to Itsuki, but he got overwhelmed by four girls around her...

Fuutarou Uesugi heads to the Nakano Family's Residence once again where he meets Miku Nakano, who lets him enter. As soon as he tries to teach the four, Nino Nakano steps into the picture and makes everyone, but Miku leaves. After realizing he had left something in the apartment, he enters and soon finds himself in a compromising situation with Nino after saving her from getting hurt. Fuutarou then learns the reason about Nino's distrust towards him after a short conversation between them.
