From Selene Scans:
Its about this girl Ann-chan who, after a traumatic event with love, doesn't think she can find it anymore.

Miku is on the same tennis team as her childhood crush, Tomo-nii.
Not only can this guy kick ass in tennis, he's also good-looking and super nice! The only thing that Miku doesn't like about him is his brother, Natsume. Completely opposite from his older brother, Natsume is known to play girls, and be a basic cocky pain in the neck.
But one day, Miku finds out something about him that ends up shocking her to no end...!!
