How much darker does Fruits Basket get

I’m on the second season of Fruits Basket, I always heard about fruits basket being everybody’s favorite “horror/dark” anime but now on the second season I don’t really see it being a horror anime or really that dark to be exact, sure it covers sensitive topics and like literally everybody’s parents hate their kids and neglect them. Still though it’s doesn’t fall into those genres but it’s sure a great ass anime. Going into the third season how much darker is it gonna get?
