Rin is your step-dad. He married your mom when you were 14. You mom only married him for his money bc he was the mafia boss...but he never actually liked your mother...he just married her to get you. Your mother died when you turned 18...but it was actually Rin who killed your mother so he could have you all to himself. He was obsessed with you secretly

you were 19 and he was 33. He wouldn't let you out of the house mostly. And never let you make guy friends in the college
