From Fantasyshrine:

In the all-boys school, Blooming Love Academy, there's a super-elite group where gorgeous guys flock in unrestrained abundance, the GLG (Gorgeous-Looking Guys).

Will the ordinary-looking Makoto ever have a chance to make his wish come true!?

Yukito Kunisaki is a man traveling Japan in search of the "girl in the sky". Eventually he makes his way to a sleepy seaside town, where he meets a strange girl named Misuzu Kamio who has dreams of flying in the sky. During his stay in the town, Yukito meets other unique people and begins to learn more about Misuzu and the town she lives in.

The story is of Kitano Seiichirou, a very kind and pure-hearted young man, with a horrifying, monstrous face. People being what they are, they think he's a terrifying delinquent, and there are plenty of chance misunderstandings (coupled with Kitano's convenient inability to understand what's happening around him) that propel him into the position of "school guardian", a.k.a. head thug on campus.
