||The twin brothers Susumu and Tsutomu have been friends with the girl Sakura since they were kids. But when Tsutomu mysteriously disappears at the age of ten, Susumu and Sakura begin to drift apart. What Sakura doesnt know: Tsutomu has returned, not as a person, but as the mirror image of Susumu. That is, whenever Susumu looks in a mirror, he sees his brother who talks to him. Thus begins a bizarre love triangle between Sakura, who torments the poor Susumu as much as she is being tormented by her peers, Susumu, who keeps thinking he has to save Sakura because he likes her, and Tsutomu, who despite being stuck in a mirror pulls everyones strings.
