Young Master Su, Your Wife Wants a Divorce

Synopsis: A deal forces her to marry him. At their first meeting, he sneers contemptuously. "I'll give you all the respect due to the eldest daughter-in-law of the Su family, but don't even dream of getting close to me. You're filthy. Just be a good Mrs. Su. If you try anything, I'll make short work of you."

She bites her lip. "All right."

It turns out you shouldn't speak too soon. The face-slapping comes fast.

He fawns over her. "Honey, I did well today, right? If anyone dares bully you again, I'll take him down in a heartbeat."

This time, she smiles and says, "All right."
