I'm Looking for a Story About a Young Lady and a Poor Boy.

It is best if there are misunderstandings or conflicts between the male and female protagonists at the beginning and the female protagonist has traveled through the book or been reborn. However, after the heroine travels through the book or is reborn, she should not humble herself to please the male protagonist to increase his favorability. It is best to have a clear-headed character with some bad intentions. It may seem like she is being sophisticated, but it is actually for revenge.
