Junjou Karen na Oretachi da! v1
I swear I've read this story somewhere before.
Uh, so this is a volleyball manga about a self-centered setter, who got kicked out from his team for being a jerk and a short guy with a super jump. They hate each other's guts but are forced to play together and the new team that they've joined is a former power house.
