I can't remember this one specific manga I once read. Can you help me out? The main hero is a small guy with a scar on his face, big eyes and messy black hair. He's always called "ugly" by the girls in the school (the girls in this story are seriously scary). He is being hit on hard by this really handsome, tall guy. Then it turns out that the tall one used to be fat and bullied and our small hero was protecting him - this is were he got the scar from. And then we learn that the fat one went to a freaky camp sort of thing in order to lose weight.
Do you know what manga I'm talking about? Please help me out here, I'll be forever grateful!

I 'm pretty sure it's Aitsu no Daihonmei

It is! Aah! FINALLY. Thank you so very much!
