Diary is to record what happens every day, but Liang Anqi (Charlene Choi)' s diary is to record what will happen in the future ... to record the "facts" she imagined! Yongna originally had a happy family and a lover who cherished her. One day, Yongna came home and found her lover Yakun had left without saying goodbye. Yong Na can't accept Yakun's silent abandonment, but she tells her friend (Liang Luoshi) how to love Yakun. Yayi actually instigated Yongna to retaliate against those who had betrayed herself! One day, Yongna met Yakun in the street. It turns out that Yakun never knew her. Everything is just Yong Na's illusion. His real name is Hao Wei (Shawn Yue). Yakun, whom she missed, died in a traffic accident two years ago. Yongna cried all this to Hao Wei, and Hao Wei loved her out of pity. They lived happily together, but since then, Hao Wei's personality has become weird, and he is even more unwilling to go to work, saying that it is enough to be with Yongna every day. One night, they were having a candlelight dinner in the house, and it was raining outside the window. At that time, Yongna thought it had something to do with Yakun, saying that Yakun died of cancer two years ago. Hao Wei felt very strange after hearing this. Hao Wei questioned Yong Na's inconsistency. Yong Na took out her diary as evidence and read the page on the day Yakun died of cancer. When Yongna read the last paragraph of the diary, she suddenly walked up to Hao Wei with fierce eyes and questioned Hao Wei's love for her ... Who is right or wrong? ◇ Behind the scenes: The filming originated from Hell, which made "Peng Brothers" (Peng Shun and Peng Fa) a horror film in China film industry, spying on people's deep fears, and also made "Peng's horror film" very popular in Hong Kong and Southeast Asia, and its imperial heroine Li Xinjie was even named "Ghost King". Peng Shun's "Delusion" reflects the entanglement and cruelty of the emotional relationship between people. According to Peng Fa, the idea of "delusion" comes from a very unpleasant love experience before my brother Peng Shun and Li Xinjie fell in love. It is from his real experience of bumpy love road that he conceived such a horror story between lovers. Considering that people often do strange things when their emotions are hit hard, some supernatural elements are added to the film. Regarding the new attempt of the Peng brothers to enter the mainland big screen for the first time, the content of "ghosts and ghosts" will no longer appear, but a "panic suspense film" as the producer of two films, saying: "The debut of the Peng brothers is actually an action film. We don't just shoot a horror film, but we don't know whether it is lucky or unfortunate after filming Hell. The whole world likes us to make this kind of films, and then we also made a lot of horror films, but we won't make them for the time being in the past two years. These two movies won't be haunted again. Delusion is almost a romantic movie. "
