Basically Black Prince and Wolf Girl, which means a toxic relationship that isn't to strive for.
The ML has a foul mouth and is supposed to be a sadist, but his attitude is more of a spoiled rich kid. The FL is naive and I feel like she needs a little more backbone and stand up for herself.
The love story in itself has some interesting but cliche aspects, I would say it can be greatly improved upon.
