From the way I read it, it seemed more like the MC contacted the father after the waka mentions he has some feelings for the MC. In order for it not to get complicated, the MC, through the info broker, told the father and the father paid for the split up + to bribe him to stay silent about the whole ordeal. Idk thats just how I interpreted it.

People do realize the MC isn’t some saint. He was being paid by the young master’s father secretly to sleep with his son on top of being paid by the young master. It’s pretty clear the father prefers to control his son’s bed partners, but his son doesn’t know this. Likely the father would rather his son’s bodyguard who’s already loyal to the family, and predicable hence why MC calls him. It’s just a bonus our MC felt he could orchestrate his plan and cut ties with his client before feelings were involved as I’m sure this was really what spurred his actions. He gets paid twice for literally just doing his work as a sex worker and being an opportunist. It’s a two birds with one stone situation that our young master finally gets to be with his unrequited love is none the wiser what goes on behind the scenes. It’s kind funny people are making the situation to be some big kind gesture. It’s just being practical.
