These were all her genuine thoughts, arising from her instincts.
She didn't want to deceive anyone, truly didn't. Every time she saw Gu Yuying, she always felt a sense of guilt.
Especially now that Gu Yuying seemed to believe her and was very considerate of her daily needs. This made her even more unsure of how to face herself. She actually wished that Gu Yuying would doubt her; that way, she wouldn't need to carry so much guilt.
This was probably Qin Lang's plan—to specifically find someone like Guo Yahan. Other than her act of saving someone being fake, all the other information about her was real.
One must understand, finding Guo Yahan had taken a lot of Qin Lang's effort. He needed to locate a woman with connections to both Jinyang and L City, and twelve years ago, her family's residence had to be near the location of the incident involving Gu Yuying.
Moreover, this woman had to be simple, with a pure and kind nature, yet financially needy and in urgent need of money.
