Yakyuubu no Hino ni Koi wo Shita.

"If I'm going to fall in love, I definitely want it to be with a guy who's as dazzling and charming as a prince!" With that ideal in mind, Risa meets Hino, a classmate who's on the school baseball team, and she sees a surprising side of him. Ever since then, Hino has made her heart race, despite him having zero romantic inclinations, being single-mindedly focused on baseball, the total opposite of a charming prince...?! This is a story of an unexpected case of puppy love over a guy who otherwise really irritates her!
