[Since every story about a real and fake heiress has a fiance, I had to change this to romance.]
Blurb:
When Qiao Yiyi first got bound to the System, she was thoroughly unwilling. She was a bright, beautiful young woman, adored by her adoptive parents, with a reliable best friend and an adoptive brother who was a rising star in the business world. She'd gotten into a good university, even if it wasn't one of the top 985 schools, so why would she go looking for trouble by playing out some real-and-fake-heiress drama?
But with the System threatening to erase her, she could only grit her teeth and agree to be bound.
To save her own skin, Qiao Yiyi crammed a whole series of novels about real and fake heiresses, wealthy-family feuds, and domineering CEOs. But all her eager preparations crumbled the moment she met the fake heiress.
Lin Xiaoxue wore her hair in a neat ponytail and a white lab coat. She formally welcomed Qiao Yiyi, then hurried off.
Behind her, Lin's parents remarked that Xiaoxue had been a genius since childhood, skipping grades all the way through college and earning her master's and doctorate in just two years. She had published her papers in top journals, and last year had been recruited directly by the National Academy of Sciences. Now, at just twenty, she was already leading a research team on her own.
Qiao Yiyi: "..." She was in a daze, and utterly crushed. At twenty, Xiaoxue was like this, while at twenty, she was... Waaaah, how could the gap between people be this huge?
Just as she was falling into self-doubt, the System's cold voice rang out in her mind.
[Ding! Host detected back at the Lin residence. Issuing first mission.]
[Lin Xiaoxue pretends to welcome the heroine home, then has the servants prepare shrimp that will trigger the heroine's allergy. She feigns ignorance and serves it to her. When the heroine refuses, Lin Xiaoxue pretends to cry, making Mr. and Mrs. Lin furious. They force the heroine to eat the shrimp, leaving her arm red and itchy all night.]
[Mission: Refuse to eat the shrimp and expose the white lotus's sinister intentions.]
[Mission success: Reward of ten tubs of whitening mud.]
[Mission failure: Erasure!]
Qiao Yiyi: "..." Seeing Lin Xiaoxue turn to leave without a care, she panicked, lunged forward, grabbed her around the legs, and wailed at the top of her lungs.
", Sister, save my life!"
