Looking for a title of a book

So this is a BL book does anyone know the name of a book where the main character was basically reincarnated into a BL book and he was reincarnated as the evil landlord and his tenant is a guy with two little brothers that he’s taking care of with a huge debt, and in the book the mafia boss is supposed to fall in love with him, but end up liking the main character I would really appreciate it if someone could tell me the title that book
