LF BL manga

Looking for this manga the plot is about a "trainer" who wants to be trained, it's a buff uke×nepo baby small top. Basically the uke is an orphan and someone adopted him from a street. The man that adopted him is working on an underground human trafficking (that is fuvk up I know but it's done with proper manner idk?¿) and when the uke grows up he works in that underground operation as a trainer who trains people to be masochist to appease their "master" but he himself wants to have a master also but he's too "hunky and buff" to be a slave. However this seme sees him and he sees how jealous the uke is when someone got their own master and the seme likes hunky things so they fuck and he brought the uke and the story progress (Why I'm reading this?! Sorry I feel guilty but I like their love story Help me find it, also you never saw me writing this)
