Her relationship with classmate Liang Runsheng, who had experience with prostitutes, was originally all for the sake of "saving the country and weeding out traitors." However, Wang Jiashi was met with snickers from her classmates. Ironically, it was only when she was with Mr. Yi, who was both old and bald, that she could find inner relief and liberation, "because everything had a purpose." Unexpectedly, Mr. Yi suddenly returned to Shanghai, causing the assassination plan to fail. After the Pearl Harbor incident, the school moved back to Shanghai, but Wang Jiashi stayed in Hong Kong because she no longer wanted to face her past. Two years later, her classmates called on her again to complete the unfinished assassination mission in Shanghai. The novel unfolds after Wang Jiashi arrives in Shanghai, appearing at Mrs. Yi's mahjong game with her "girlfriends" under the disguise of "Mrs. Mai." Wang Jiashi plans to lure Mr. Yi to the assassination location, a jewelry store, under the pretext of repairing an earring tonight. She is uneasy, makes an excuse to leave, and waits for Mr. Yi at a café on Nanjing Road. During the anxious wait, all sorts of complicated emotions from the past flood her mind. Wang recalls the various ambiguous moments with Yi and the experiences of the past two years, leaving her with a mix of conflicting feelings and hesitation. Finally, Mr. Yi arrives. Despite being ruthless and cunning, he never suspects that this young lover, with whom he has been secretly involved for two years, could be part of an assassin's plan. They finally arrive at the jewelry store. On the way, Wang Jiashi ponders whether Mr. Yi has ever truly loved her, consumed by the petty concerns of a woman caught in uncertainty, completely detached from any thoughts of national or personal vengeance. Outside the jewelry store, the assassins lie in wait, while Wang Jiashi's heart is filled with immense anxiety.
