I really like enemies to lovers trope but this one, not so much. There was no build up to the relationship aside from ML raping her to the point of submission. Plus, they made the FL the "strongest" knight but she didn't even put up a fight when the ML raped her the first time. What's the point of portraying her as a strong knight if she can't protect herself.
