Kikukawa Shiori wakes up from a motorcycle accident only to find out she's lost her memory! Try as she might, she can't remember anything about the yankee-looking boy who claims to be her boyfriend, her kind-hearted and good looking older brother, or her aloof and introverted younger sister.<br /><br />When she goes to school for the first time since her accident, she overhears people talking about her---and the things they say aren't flattering. From what she hears, she was a terrible person before the accident. Was she really as horrible as they're making her out to be? And will she ever get her memory back?
