She didn't hate him but she warns the mc that he's not right in the head like his mother, he'll do what he wants with no remorse as long as he gets what he wants. The Duchess does care for him tho as shown before he became a weirdo but now that she realised that he's obsessed with the FL she's tryna warn and protect her
So wait did the ML's father cheat on the Duchess (his wife)? Or did the ML's mum in some way charm him or something? Is that why the Duchess hates the ML??
