What’s this?

In color. Girl has blonde hair dyed pink at the ends. I think she was a servant? They cut off the pink and pretend she’s the noblewoman getting married. She’s sent off. The dude rapes her on their first night. No clue how but she fell in love with him. There’s a timeskip and years later they have a son. The son is kidnapped, I think, and that’s as far as I remember. I think the cover was of the FL holding a sword. Idek why I wanna know but I do lol
