He is mine (Jeongcheol)

The Choi family and the Hong family have been the two leading families of the mafia world. They've built their legacies from nothing, and will do everything in their power to keep them.
Seungcheol Choi has always been taught two things, always fight for yourself and never trust a Hong. He never planned to, growing to hate the Chois just as much as his family did. But when they two families are forced together, the hatred he always felt for the Hong's becomes much more complicated.
Jeonghan has always known about his family's business in the crime world, but he has never wanted to be apart of it, at least not like his older brother Joshua did. But when a fatal accident leaves one of Joshua's family members dead , he is left with no choice but to join the business he's been so desperately running from.
