Taehyung Mafia

Taehyung and Aileen had an arranged marriage, a deal-making arrangement. Taehyung is the head of a Korean mafia. He is tall, dark-skinned, muscular, and incredibly wealthy. He is 35 years old. Aileen is a famous doctor, beautiful and delicate, with fair skin and a perfect figure. She is of average height. She is 25 years old.
They have a five-year-old daughter named Marilyn, who is very cute and looks a lot like Taehyung.
They treat each other coldly. Taehyung doesn't care about her at all, not even his daughter. Aileen has never seen him hug their daughter even once, and he's always distant. Even Marilyn is afraid of him. Unlike Aileen, who spoils their child because she believes Marilyn doesn't deserve to live with people involved in the mafia. And Marilyn, unlike the other children she's with, is quiet. While she's playful and mischievous sometimes, she's genuinely afraid of upsetting her father.
Taehyung has enemies who constantly threaten him, but now they've gone so far as to kidnap his child.
