This is pretty dumb. Clearly the mc isn't idiot or oblivious. He clearly knew what was coming when they wen't to that feeding place of the snobs. It's also stupid and cringy for him to showoff his wealth like that. It would made most sense to have hew collar removed, buy her new clothes, and teach her to behave like a friend/assistant (or at least like a normal person/human ffs) etc.
