I think Dion's mom (the short-haired maid murderer), just likes messing with Roxanne's mom, seeing how weak-hearted she is. I'm surprised that she could live long in that house.
The fall of this super evil family was actually in the first volume. There are 4 volumes of this. By the 2nd volume, the Kassis was already in love with Roxanne. He is very passionate and loyal to her.

I know they’re half siblings but damn that man is attractive and totally my type lol. Does he like Roxanne? Is she the only person that can get a reaction from him ?
