I don't remember exactly the history but it was something like this. The ML was infiltrated in the FL's house as a butler and dating her, but he was infiltrated to expose her family. When her family is exposed they are sentenced to death I think and she asks to be killed too. She ends up reincarnating as an orphan child and when she grows up, she goes to work in ML's house. If I remember correctly the ML was the emperor.
I'm sorry if it's messy but I don't know how to explain 😔. Hope someone can help me.

The plot really reminded me of The Wolf Lord's Lady

ohh it's that one, thank you so much 😁
