Two girls. The same age. The same name. Yet they couldn't be more different. One is a naive serial dater who always hooks up with the worst guys, the other a bitter rockette with a violent temper and a lonely past. They both move from their small-town homes to Tokyo, chasing their dreams of love, music, and self-discovery. Their fateful encounter changes their lives in ways they never imagined possible ... to the point where life becomes unlivable without the other one there.
