The Beloved Darling of the Duke's Estate

[It's not good, don't click on this, aaah!!] [Back then I was young and foolish and messed up a great premise and setting. Don't read it, aaah, boohoo! Let me do a three-hundred-and-sixty-degree Thomas-the-Engine spin to lure you in: don't! read! it!] Blurb: A man came to Mount Qishan, carrying a token and asking to see Qi Bo. Yingzhi took out her master Qi Bo's belongings and had a look, then packed her things and went down the mountain with the man. Word spread like wildfire through the capital: the Crown Prince had brought a fairy down from Mount Qishan, riding a white deer, with cloud-dark hair and snow-white skin, as if she were glowing. A few days later, the Duchess of Zhenguo stepped forward to explain that there had been a mix-up during the birth all those years ago, and that this little fairy who had grown up far from home was the true daughter. Everyone waited for the drama of the "real and fake heiress" to unfold, but who could have guessed... The Duke's household remained as harmonious as ever, and Yingzhi, who was "ill-mannered" and "raised in the wilds," became the family's beloved darling. The Crown Prince has something to say about that: Cen Yu: She's obviously my darling. Reader's guide: [Content warning] [The story is a slow burn, and the heroine needs time to adjust at first] [Content warning] [The heroine gets better and better as the story progresses] 1. A black-hearted-on-the-inside male lead x a wild yet sweet heroine. Alternate universe, no cultivation. 2. The real and fake heiresses get along well and live in harmony. 3. A bedtime read.
