Arrête de me chauffer, Nagatoro !

Senpai is a nerdy high schooler whose manga work is discovered by some loud girls in the library. They all tease him, but one among them, Nagatoro, takes it further than the others.

After seeing Senpai get mocked for his inability to run, Nagatoro takes him out jogging to try to whip him into shape. The culture festival is coming up, and Senpai needs something to present for the arts club.

Senpai doesn’t have any confidence that he can win against the art club president. Nagatoro and the gang try to cheer him up, but the president’s art is just too powerful. Nagatoro offers to model for Senpai.

Senpai isn’t sure he can beat the art club president in popularity at the culture festival. Nagatoro and the gang do everything they can to help him.

Nagatoro is still torturing Senpai, laughing at his choice of manga and at how he talks to girls, and trying to get a reaction out of him by having him put her stockings on her.
