What anime has a short green haired first year in high school where he dates a blue haired girl?

this anime has something like magic in it and the blue haired girl is like a master of it (i think she might of made it or profected maybe) and on his first day of transfering to this school he sees this blue haired girl surrounded by cherry blossoms. He approaches her and takes a cherry blossom from her hair and she asks him out. btw there is also a older guy who is trying to get the blue haired girl to be his because he is "surperior" than the green haired boy (and the girl is rich)
