"Rockin' Heaven" by Mayu Sakai 6 volumes-ongoing
Sawa chose Amawa Gakuen because of their cute uniforms. But she founds out that it was only that same school year that they opened the school for girls. And she happens to be in section 1-G or as what the other students call as the garbage class. The art is beautiful and her classmates are cute especially...(you'll know who). The things he does for her is ssso sweet. Look out for the signs. Some are subtle and some are oh-so-obvious.
