Aw man I thought this was discussion about which is actually better. XD I choose adopted daughter since you can actually get to know her before adopting. a real daughter might not even care if your dying because you can't vet her personality your stuck with what you got. XD Yup I started it!! XD
The Yandere Comes During the Night - Here the MC is fake daughter, and she endlessly slaps people in the face. It's really cute and the ML is of course great. Little One Tears the Villain's Script - I haven't read up to meeting the fake daughter yet. MC is the real daughter.
Return of the Swallow (highly recommended, but very long!) Every Vicious Woman Needs a Loyal Man (short and sweet) Pampered Poisonous Royal Wife (honorable mention, cousins)
I don't trust my twin sister (KR) - kind of like a villainess revenge novel but not really (?). My sister told me to give up my fiance (JP) - kind of like an afterstory of a villainess and what happens but the villainess is the heroine now loool sounds familiar?. The story is revolving more on what happens to her but the reason why shit happened is because of her sister. Aye typical plot mayhaps. My Fiance is in Love with My Little Sister (JP) - The focus of this one is more on the tragedy and the plot is decent ig. The sisters are not really against each other but there's a bit of conflict regarding the fiance.
Can We Become a Family? MC adopted to marry the Crown Prince on behalf of the Duke's ill daughter. Perfect Fiancé Transmigrated into a novel after her death, MC has an engagement with the ML, that was arranged between their families. After the revelation of her identity as the adopted daughter swapped at birth, she had no right to the engagement.
I wish there was tag for it, then you could find something Maybe there is a tag for switched at birth?
I have found another fake/real daughter story, but I haven't progressed far in it. Perhaps you haven't read it? Addicted Pampering You. Next time, give us the list of novels you have already read so it can make things easier to recommend for you.
