Read The Real Daughter is Back Manhwa
Summary: 진짜 딸이 돌아왔다 / The Real Daughter is Back
Helga Yttri, a half-noble lady who inherited the blood of a lowly maid. A bastard child who was swapped by the Duke’s maid; a Fake child. Helga gave her everything to be recognised as the real daughter. “Your Grace! The real Young Miss is alive.” “Her name is Hyllian…!” Helga prayed to God countless times so that the real Young Miss never returned. ” …don’t come back, Hyllian.” “Don’t come back, please.” She wondered if her prayers failed to reach God because she was a fake daughter. “Dear God, I’ve been praying countless times.” “I asked you never to let ‘that child’ return.” The prayers she howled until her throat went hoarse was all in vain. “The real daughter of the House of Yttri, Hyllian… The child who will destroy my whole world.” The real daughter is back.
It just got interesting as of chapter 19. If you don’t like sibling comparison/abuse this may not be for you but I can tell it’s gonna be a good revenge story she’s already starting to make use of her plans instead of waiting 100 chapters
I already loved it before chapter 19, but I can agree that if you don’t like sibling comparison/abuse you probably won’t like it too much I think that after you get started you will love it even with the sibling comparison/abuse.
