Old Korean manga(?) that is full cliche so (big warning here). Girl is well not pretty and the np is super handsome. This is for a more physical appearance sort comparison to beauty and the best I think. Anyway the situation is reversed. ML must end up seeing beyond the physical appearance.

Can't say it's a straighout beauty and the beast. But there's a beauty and a beast in the story. Not gonna say more bc of spoiler reason.

There's no beast but they're a rumored tyrant that a book lover heroine was forced(? Or end up) marrying. She discover that the guys has reasons and is not such a bad guy.
