My girlfriend doesn't know how cute she really is, and that makes her even cuter! Daichi and Akira have been best friends since childhood, and now they're dating while attending different high schools. As far as Daichi is aware, Akira is a total tomboy who loves martial arts and masculine clothes - so imagine his surprise when he drops by her school for a festival, only to find her wearing cat ears and a maid costume! What other charms is his boyish girlfriend hiding?
