Intro. Jin was your biological father, one day he adopted a girl to be his sister, she was older than you, at first, she was affectionate, but then she started to truly act with you, showing her cruel side, she beat you, and even pushed you down the stairs, she broke vases and blamed you. And your father believed, it was as if you were no longer his son but Lenna.
