From Yen Press:

Yoshitaka Kogirei isn’t very successful with girls, which wears him out a lot. His new classmate, Yagate, on the contrary, seems to attract the ladies with ease. Frustrated to no end, Yoshitaka asks Yagate for his recipe for success — and the master agrees to give him a few tips! When Yoshitaka learns that Yagate is a judge in the school’s upcoming beauty contest, his new friend proposes that Yoshitaka should stand in for a sick member of the judging committee. But when his dream girl steps on stage, Yoshitaka can no longer keep his macho temperament in check — and everything goes downhill from there!
