Jin Sigmon Keriozo loves to play around. When I say play, I wish it is something like playing dutch ball or computer games but its not. He loves to give mixed signals but in the end he broke every girl's heart into pieces.
But one day, a girl named Zeriny Isabel Husia got his attention. Why? Because every time they talk, this girl can't remember him although they see each other everyday because they are classmates. He thought that he's being fooled by this girl so he got a plan. He'll be an investigator on his own curiosity.
What will he find out?
