Gu Zi was rather indifferent to Mo Li's betrayal. Mo Li was the kind of person who would only succumb to her own interests. Lin Miao was unable to control her. According to the original novel, Lin Miao would eventually fall into her own trap.
Moreover, Lin Miao's theft of the three thousand yuan betrothal money was not only witnessed by Mo Li. There was more than one line of evidence, so Gu Zi was not worried that the truth would be concealed for too long.
When Mother Lin and Li Hua remembered that Mo Li had already reneged on her promise to testify for them, they realized they had to hide.
Mother Lin expressed her concern, "I wonder how long this investigation will take."
Gu Zi replied, "Don't worry, the truth will come out."
Suddenly, a familiar and cheerful female voice came, "Ah, Gu Zi, what are you doing here? And this must be Aunt Lin? Hello, Aunt Lin."
