Help me...pls

Does anybody know this one yaoi manga, these 2 boys are students at art college, they are roommates. The top boy is very talented in art, he's famous and you know all the pretty boy's things. When he's doing his work in his room he wouldn't get out (or let the other boy get in) at least not until he heard his childhood friend called. The uke boy is kinda opposite to him...yea. There is this scene, a professor or so told the uke boii his work is bad, messy and such, after that old professor left, when the uke is kinda lost in thoughts, the top boi appeared and told him he liked his art, he said it looked lively (or so, i don't remember clearly). This description is not clear at all but i hope you can help me (〜￣△￣)〜
