This is a unique manga to read because the main guy is the strong, dominant person in the relationship. In this manga, not only is he shorter and younger than the main girl, he's also more "girlish" than the main girl.
Our main girl, the protagonist, is very boyish yet not immaturely tomboyish. The way she acts is very realistic--she isn't some cute girl who cries over some little thing or thinks about getting a boyfriend all the time.
I've just finished volume 2, and I found that I enjoyed this series very much. I would recommend this series for people who like looking at "pretty boys." :)
