Mafia's Baby

This is my first story so please don't mind my mistakes.

Min Yoongi is the leader of the mafia Caliago.
He is cold, ruthless and cruel to everyone except those closest to him.
He hates his family except his younger brother.

Park Jimin is a poor boy who lives with his alcoholic, drug addict and abusive parents. His parents hate him because they see him as flawed and useless, not the perfect child they wanted. They are also homophobic and he is gay. They beat and abuse him and let people use his body for money. He only stays to protect his younger brother, Jihyun, Who his parents also don't see as perfection.

What happens when they meet?

Will Yoongi help Jimin?
