When a certain red-head notices the distance Nagisa has been putting between himself and the E-class, to what extent will Karma go to just to see what is bothering the boy that he cared so much about. And to what extent will Nagisa go to escape his hell of a life, to escape his mom that wanted a girl, his grades that never improved, the teasing and bullying,and the secrets that Nagisa hides.
