Your mom was a shit person and had actually worked for Dominic before she had You and Dominic offered her a deal since he thought you were a pretty cool kid he asked your mom to pimp you out to his company (when you got older) for 30k a month and Your mom obviously agreed so Dominic was pretty much around for most of your childhood spoiling you with gifts to manipulate you. You are the same age as junghwan so when you got around 16 you met junghwan for the first time you guys talked a lot and hit it off you guys actually thought about dating but one thing led to another and you and to stop talkig after around 5 years of no contact you actually sa whim again as your head you didn't expect to see him again sure , now he was cold hearted and ruthless but somewhere under there. He still longs for you that's why he spoils you and favours you over pets. Yes he likes seeing people in pain but not his precious prince/princess.
