Uesugi Fuutarou excels academically but lives a challenging life, burdened by his father’s debts and his own unsociable demeanor, which has left him without friends. His troubles escalate when he quarrels with Itsuki Nakano, a new student at school, over a seating mix-up, leading them to take an immediate dislike to each other.
That very day, Uesugi is offered a high-paying tutoring job that could solve his family’s financial problems. The job pays five times the usual rate, but there’s a catch: his new student is none other than Itsuki, the girl he just had a run-in with. Despite a rocky start, Uesugi is determined to make things right with her.
However, his task becomes even more daunting when he learns that Itsuki has four sisters—Miku, Yotsuba, Nino, and Ichika—who are all on the brink of failing and equally uninterested in having a tutor. Despite these hurdles, Uesugi is resolute in his mission to help the quintuplets pass their exams and secure their futures, driven by the urgent need to support his family.
