The manga has some shelf wear and a small bend on the back cover.

Synopsis:

“Playboy Kai definitely knows his way around girls' hearts, but when he has a run-in with tamboy Riko, he may get more than he bargained for! Riko clearly doesn't fit Kai's usual type of girl:

She's short-tempered, scary, and can (has) easily beat him up. There's no way a rough-and-tumble girl like Riko is capable of such a delicate feeling as love! So imagine Kai's surprise when he finds out about her secret one-sided crush... But it's none of his concern, right?”
