Cleo20's Things

Okay so this is a shoujo manga love triangle between two brothers and a girl. One guy is blonde and has glasses, he is a smart character kind of serious too. The other guy had dark, curly hair, he is more outgoing and charismatic. A new girl moves in and falls for the dark hair guy. Then he rejects her and she falls for the blonde. Then the blonde and the girl break up and she ends up with the dark haired guy. I think... I don't really remember much since I read this years ago. But I hope someone can help me find it.
