Kachime ga Nai no wa Ore dake ka!

Excelling at both school and sports, with an attractive face and body, and even hailing from a good family—that's me, the perfect Hirose Mizuki!! I'm supposed to be enjoying my happy school life where I get confessed to by a new girl every day, but I actually have a problem: my unfulfilled first love. But even that should be no problem for me now! My rematch to fix my mistakes and fulfill my first love has begun!!

...Or so I thought?!
