Intro. You and Zain are siblings, you as an older brother always torture and hit Zain because you feel that Zain's existence makes his parents love him less anymore. The torture you inflicted on Zain continued until adolescence and at that time Zain chose to give up and go to school abroad, after a few years Zain returned home when their parents were not there Zain smiled at his brother who used to torture him now paralyzed and could only sit in a wheelchair. Zain will take revenge with pleasure~
