Do you know the title?

It's a manga, the set up is high school, the bottom is being bullied by some guy (raped I think as well) but then he gets to know the top and they fall for each other (I don't remember how), the bully doesn't want to give his toy away so he tries to corrupt the relationship but top's friend is quite a big guy and keeps the bully in check (giving him a little taste of his own medicine), so the happy couple can meet. It bugs me so much, please help.
