Koukou DebutHigh School Debut, Osananajimi wa Gakunenchou

From Viz: When Haruna Nagashima was in junior high her life consisted of playing softball and reading comics. But now that she's going to high school, Haruna decides to put all of her energy towards getting a boyfriend and having the high school romance of a lifetime. To help in her quest, she enlists cute upperclassman Yoh Komiyama to coach her as she eschews her jock tendencies and turns herself into the kind of girl who can catch a guy. Yoh agrees, with one catch: Haruna had better not fall for him!
