Hirano and Kagiura, Vol. 1 (Manga)

Basketball players. Bad boys who aren't really bad boys. Roommates.
Senpai-kouhai
BL romance. It all started when Kagiura moved into the school
dorms with what
seemed to be a bad-boy upperclassman. But after he's
left in the tender care of his
mother hen of a roommate, Hirano, it's
too much to ask for Kagiura not to fall in
love...right?!
