@Haikanouch_ique Manhwa logic doesn't allow people to have two daughters. If there are two bio sisters one must be hidden, unloved or some nonsense. And in other cases, like this, one must be branded fake.
Why do 'reincarnated in a book' heroines always turn out to be someone travelling back in time.. -_-
@tar0t yea but there's one it's called "the real daughter is back" it the, same but the long lost sister who is the female leads sister ,she actually likes her and has no bad intentions it's a good one hope you read it
