The beautiful port city of La Spezia. After leaving an orphanage and serving as a nurse on the battlefield for three years, Monica is hired as a tutor by the wealthy Mallett family. On her first day in a strange city, Monica encounters a familiar face.

"I'm sorry, but I don't have that name."

She thinks it is Sol, a soldier who took great care of her on the battlefield, but the man replies that he doesn't know her. This wasn't the man she knew, but if she meets him again, they will know each other. How come, every time they meet, his name and personality change? The only thing that remains constant is his appearance and the scar around his eye. Identical twins? Or perhaps he has multiple personalities?
