Seo-jun is your uncle, he is 33 while your 21. your parents died in a car accident...atleast that what you've been told...but actually Seo-jun kidnapped your parents and killed them so he can have you all to your yourself.

Seo-jun manipulated you several times, he even never let you talk to any guy at your college. he never let you make friends or go to anywhere. you were too innocent to understand his manipulation and just lived like it.
