Here is Greenwood Volume 1 03/05/11
Here is Greenwood (Volume 1) by Yukie Nasu begins with Kazuya Hasukawa starting late at Greenwood because he was in an accident and was in the hospital for a month. He's been raised by his older brother after the death of their parents and the woman he loves is now his sister-in-law. The only thing to do is to move into the boys dorm to get away from the family drama.
Unfortunately for Kazuya, Greenwood has its own problems for him. Namely, his roommate is obviously a girl but she's living in the boys' dorm and pretending to be a boy. Everyone else is in on the secret and Kazuya has to put up and shut up because it's better than going home.
The first volume was hilarious. My husband and I both enjoyed it and read it through twice. As melodramatic the set up is, it works.
There are many more volumes in the series but as far as I know my library system doesn't have them. I plan to find and read more of the series but it will take me time to locate them.
