Looking for a manhwa

Hello, I am looking for this manhwa but I dont exactly remember the last time I read this so Im so sorry if my explanation is bad

It was this story about a woman, who has rlly strong holy powers (?) But she never reveals this to anyone so she always gets tasks that maybe don'tmake a lot of money. Then, She gets tasked to take care of a prince who is very sensitive to noises and people surrounding the mansion for $$$. At first, i think he didnt like her and had her in the farthest room away from his but then he started to like her and follow her directions and was glued to her.

Idk if I'm mixing this up with another manhwa but I believe he was going insane from being treated like a war dog (?) Because he was used for war. So she was tasked to make him "more human" and somewhere down the line she was taking care of two of them but then the second guy was sent away.

Im so sorry for the bad explanation
