Asuka Masamune is a guy who loves girly things--sewing, knitting, making cute stuffed animals and reading shojo comics. But in a world where boys are expected to act manly, Asuka must hide his beloved hobbies and play the part of a masculine jock instead. Can Asuka ever show his true self to anyone, much less to Ryo Miyakozuka, the girl that he's falling for?

Asuka engages in a battle with Suzaki Oji to see who will get the most Valentine's Day chocolates! As Oji seduces girls left and right into giving him chocolates, Asuka wonders one thing--who will Ryo give her chocolates to?
