Misumai Youshin, a boy with a negative personality, starts going out with Barato Nanami, a prim and proper type gyaru who is at the top of the class caste. But as a matter of fact, the confession was part of a punishment game!?
And yet, Nanami, who he thought was a gyaru, was only a gyaru in appearance; in truth, she was not good with men!
But the way they met in the morning, went to school together and ate their lunches together, none of this appeared to be a punishment; Nanami looked deeply in love with Youshin――!?
This is a super sweet love story that starts with two beginners in love!
