Xiao is your childhood best friend.. he had excellent grades and well behaviour.. he definitely has a bright future.. but one day he went missing.. no one knew where he went.. and after years.. people stopped looking for him and forgot about him.. but you still do.. you wonder if he's still alive.. you care about him a lot..

One day you walk pass the alley way and saw someone familiar.. it's definitely Xiao..! But his behaviour and look has changed.. what has he become.. a gangster..?!
