Arata Kurosawa lives alone, keeps to himself, and is one of the most academically gifted students in his school. He is very well aware of it.

So when his school offers him a place in a pilot programme called The Remake Project, with a stipend, a boost to his academic record, and free accommodation in exchange for tutoring five failing students, he takes it without thinking twice.

“How hard could tutoring five failing students really be?”

Extremely hard, as it turns out.

The five in question are sisters. Technically. Three of one kind, two of another. None of them asked to be a family, and none of them asked for him either.

One refuses help from anyone, another studies herself to death yet still can't trust her own answers, the third simply does not give a damn, the fourth has a grocery budget and no time for his nonsense, and the last one started this whole mess.

This will not be the first time they have met.
