Part of the plot of "Good Sir"

Lu Yuan went to the place where Jiahe's mother once lived alone and found Jiahe's mother Liu Jing. Liu Jing has now remarried and has a five-or six-year-old son. Liu Yuan told her that Jiahe was downstairs and Liu Jing looked strange. When Liu Jing's husband came back, Liu Jing took him back to his room to discuss, but his husband cursed Liu Jing for wanting to adopt her ex-husband's daughter, and drove Lu Yuan away. Liu Jing told Liu Yuan that she was crushed by Jiahe, and Liu Yuan left sadly. Lu Yuan told Jiahe that her biological mother had remarried and moved away.

Listening to Liu Yuan's nagging, Jiahe couldn't help looking back upstairs. Maybe she still has such beautiful expectations in her heart. Jiahe pretends not to care about her biological mother, hoping that Lu Yuan can send her back to the United States and find a foster family as an orphan. They parted ways from now on. Lu Yuan remembered that Jiahe had a grandmother in Shanghai, and Jiahe refused to tell Lu Yuan's address. Lu Yuan lured Jiahe to tell his address with Peng Hai's insurance money. Jiahe found the right opportunity to get Lu Yuan's passport and hid it in his underwear.
