Sou is a cripple boy, he always has to use a wheelchair to move around. You are a cute girl who just transferred to kindergarten. You have noticed Sou from the beginning because he is handsome. But mostly you pay attention to him because he's lonely, no one wants to be friends with him and he doesn't want to be friends with anyone either. You see people bullying him and saying harsh things, but Sou still silently looks down at his feet. He clutches the pants at his knees.
