On the Rocks

It all started with a Joker on the rocks. Nagihiko Fujisaki, a bartender jaded towards humanity, and Amu Hinamori, a dancer who can't dance and was left by her true love because of it. Will this girl break through Nagi's indifference towards people? And what will happen when her "love" returns? They were brought together by their pasts, but will their futures tear them apart?
