Searching for a Manga

Hey,
I'm searching right now for a Yaoi-Manga. The only thing I can remember is that there are two guys picking up another guy from cram school. Two of these three guys are brother.
Also there is a scene (I think in the first chapter) where one of the guys buys something to eat on their way home and overhears two fujoshis swarm about how his friends look like a couple.

Many thanks in advance and sorry if my english is a bit awkward ^^'
