This reminded me a lot of Gokusen. Not necessarily because of the story but how its told. Its not really one storyline till the end but each episode has its own little story concentrating on one side character (...which is being helped by the female lead).
I really liked the idea of one girl being in a school full of boys.
(I mean what girl doesn't? ^.^) Sometimes it was cute and sometimes it was a little dramatic (ok, maybe sometimes a little too dramatic). The music was catchy, the acting was great and the boys were cute. This drama has a special atmosphere. You know, when you watch those (american) movies where the lead character dramatically gives a Speech/Explanation in front of an audience/other lead character towards the end and the audience so moved by his/her words that they all cheer/kiss or whatever. This kind of atmosphere leads you through all 9 episodes. Not much romance but a lot of "fighting"-attitude, so if you don't mind a little cheesiness on the side, you should give this a try. I did and I didnt regret it.
