Crappy Google translated summary from the official raw:

Hatsune is a high school boy who looks like a girl with no "manliness" at all. However, his girlfriend is a transcendent beauty that everyone envy, and is a perfect woman who is both academic and athletic! She is proud of her ability to do everything perfectly, but what about her days when Haruga feels a little depressed because of the difference between herself and her...? An intensely sweet youth romantic comedy spent with a perfect and wonderful girlfriend!

Damn. Doesn't feel like it'll end up cooking nearly as much as Mai Ball.
