Ching Ching (played by Zeng Kaixuan) had a car accident half a year ago. She lost all her memory after waking up, but her body gradually recovered and she flew from Taiwan to Hong Kong to prepare for her boyfriend Cheng Wei's funeral. Ah Wei's friend Ah Yong (played by Andy On) sent Ching Ching to Ah Wei's residence and settled her down. Ching Ching was very grateful. It turned out that half a year ago, Ching Ching broke up angrily because she found out that Ah Wei had a third party. The two had car accidents at different places at the same time, one died and the other was injured. Living in the house where the two used to live together, Ching Ching wanted to regain her past memories. One day, she ran into Lin Qi (played by Yang Aijin), a woman who also loved to quarrel with her boyfriend downstairs. The two became close friends. Lin Qi told her that a man would only lie to you if he loved you very much. Ching Ching saw the letter that Ah Wei wrote to her in the storage room but was returned, and began to see Ah Wei often in the room again, suffering from torture. Ah Yong told her that all this was an illusion, but Ching Ching believed in her eyes. After Ah Wei's funeral, Ching Ching also planned to return to Taiwan. At this time, Ah Yong confessed to her and Ching Ching accepted it. When he tells Lin Qi the message he left behind, he discovers a shocking truth, which is closely related to whether A Wei is dead or not.
