Fmc is the MMC/his family’s servant/maid’s daughter

Looking for a book/ao3/wattpad/literotica rec where the fmc is the servant’s/maid’s daughter and the mmc (and his family) is the one employing her/her family. I want him to be cruel,sadistic and deviant towards her. Would LOVE for it be a DARK BULLY romance. The DARKER THE BETTER. And an additional point would be if they kinda grew up together/around each other and even went to school together (so he could continue his torment). Would also love an age gap and Reverse harem if possible (like the mmc and his friends). I’m really in the mood for something like this. Any genre is fine even historical romance. Thank you in advance!!!
