There are two geniuses at Ichinose Academy: Fumino Furuhashi, a liberal arts prodigy, and Rizu Ogata, a scientific whiz. Nariyuki Yuiga is a talented student who has contempt for them, especially as he’s aiming to get a "special VIP recommendation.” But then, as a condition for receiving it, Nariyuki is ordered to tutor Fumino and Rizu so that they’re accepted at their first-choice university. Nariyuki rolls up his sleeves but is dismayed to find that Fumino wants to be a science major and Rizu a liberal arts major, the exact opposite of where their talents lie. Moreover, they seem to have no aptitude whatsoever for the subjects they’re interested in. Nariyuki advises the geniuses to change their minds, but...

Ichinose Academy’s famous three-day, two-night study training camp has begun. Nariyuki and the students study hard at the boarding house in the mountains, but Rizu can’t stop thinking about her tutor.

When Nariyuki is walking by Mafuyu's apartment one day, she invites him in because she apparently had seen a cockroach. He goes inside and finds the place just as messy as it was during his last visit.
