She is accompanied by her son, whom she has kept away from her family in China. Her return is marked by the funeral of her sister, Yuan Zhihua, and her mother.
During the funeral, Zhilan meets her niece, Jingjing, who is now a grown girl. Jingjing is distant and cold towards Zhilan as she was not present for her while growing up. Zhilan is also struggling to come to terms with the death of her sister and mother, and the strained relationship she had with them.
As Zhilan tries to navigate her grief and familial tensions, she receives a message from her old flame, Song Qiyang. Song tells Zhilan that he is still in love with her and wants to be with her. However, it is unclear whether he is messaging the living Zhilan or her deceased sister.
