"... It's a shoujo about a really shy girl who is tall and has big, cute ears. The guy notices her in class and befriends her... The art is really clean and simple, kind of like Meguro Amu's.. There are so many shoujo manga out there!! All I can remember is that the guy has a lot of childhood friends? And that he joked that their names are Red, Blue, Green?.. I don't know..."

Asked by someone on the Summer Rain cbox.

I'm not really sure since I don't remember the "red, blue, etc.," part but is it possibly this manga - Stand Up! (YAMAKAWA Aiji)?

I think that might be it. I'll ask. Thank you.

No problem, I hope that's the one.

I've read the available chapters of Stand Up! a few times, and it's definitely the manga they are looking for.
