I decided to try to put it together here.
It's about the Gyusol family (Mingyu + Vernon). It's like this: Vernon was just an innocent boy who lived in his own world and worked hard to support himself at 17. His father (Simon Choi) was addicted to gambling until he ran out of money. To solve this problem, he decided to bet his son, Vernon, to a very cruel, dangerous, and heartless mobster, Kim Mingyu. If Vernon's father won, he would get a lot of money. But if he lost, Vernon would officially belong to Kim Mingyu, without the poor boy knowing anything. Vernon's father ended up losing the bet, and Mingyu was so proud that the boy would finally be his. Now, Vernon has no escape. Kim Mingyu, with his cowardice and cruelty, decided to go to the poor, innocent boy's work and forcibly rip him out of his job, making him his own, by hook or by crook. Mingyu wanted Vernon all to himself, if the boy isn't his he won't be anyone's!?
