Help find friends

Not sure if this is a manhwa now or a novel still, but the story have this fl that reincarnated (of course) and when she reincarnated she was mending her relationship with her father (I think she was engaged too but broke it coz the guy is a narcissistic dicc who ignored the og body owner) whom she thought was awful to the og body owner. The last thing I remember was she was frequently getting visited by her father's disciple that is actually the prince (shocking) but she doesn't know and thought that he was just a really rogue disciple. She hid him in her closet in the last chapter I read and gave him a sandwich as a compensation, it was fuqqin cute please help me find.
