you were a bastard child, the result of when Sujin cheated on her husband, he abandoned her and she couldn't take care of you, so she put you up for adoption when you were still a baby

you were adopted by an elderly couple and you didn't even know who your biological mother was, but you never really cared about it, for you your parents were elderly people who dedicated their body and soul to taking care of you, and not a random woman who gave birth to you

you were already 17 years old and your adoptive parents wanted to at least make you meet the woman who gave birth to you

and there were you and your adoptive parents, at the airport Sujin had gotten off her plane and smiled when she saw you so grown up, her mother's instinct already knowing it was you

but when she got closer she ended up tripping, you quickly caught her before she fell to the ground, and she smiled, the closest she had to a hug from you...
