i forgot to set this manhwa as reading so the premise the i can remember is like this:

mc is in debt. mc was referred to a job by his debtor. his goal is to be a spy to the ml's business or something. then the very first scene i remember is that mc was instructed by the house staff to deliver the towel(?) to ml while he's bathing then stuff happened iykwim. mc thought it was normal for ml to do shit with his house staff while he bathes until one of the staff was confused what he's talking about when mc tried to ask her if it's like a normal occurrence. that's all i can remember then there's this comment there that i couldn't forget. something a long the lines of "why are they oiled up" or something bc the artstyle makes them shiny looking lol

anyway pls help me
