Boys of Summer, Volume 1 (1) (Boys of Summer manga)

Bud Waterston is a decent looking guy in full hormonal bloom. He's heading for college, and imagines the sexual liberation he will face living in a dormitory full of other post-teens in full hormonal bloom. But like all best laid plans (no pun intended), nothing goes as Bud hopes or expects. His roommate turns out to be a closeted homosexual and all the good-looking girls in the dorm are interested in somebody else. When the girl of his dreams, who wanting nothing to do with him, joins the school baseball team, it inspires Bud to join, too-in an effort to prove to her she's all wrong about him.
