There is a couple, but they show up a little later. She starts out happy on her own by mistake.

Jiang Mengjin had only gone on a trip. She never expected to be turned away when she came home, while a woman about her age called her parents "Mom" and "Dad."

It turned out she was merely an adopted daughter taken in by chance, and her existence was just the result of a mistake made years ago. Everything had been a joke. Looking at the note tossed out of the house alongside her, Jiang Mengju made up her mind: she would go back to the countryside and find her parents.

But luck, once it comes, just can't be stopped. After a misfortune turned out to be a blessing, Jiang Mengju became bound to an identity System. All she had to do was sign in and complete tasks to gain new identities, which could be stacked without limit. From then on, Jiang Mengju forged a new path to wealth, bringing her parents and younger brother back to the city to give her adoptive parents a forceful face-slapping.

Gu Yanlan was furious. "This is impossible! I clearly sent her back to the countryside. How can she still be living better than me?"

Jiang Mengju: "Do you even know who you're dealing with?"
