The psychiatrist tried to hypnotize Liu Xiuyue and asked him to tell the forgotten memories in his subconscious mind. Liu Xiuyue remembered that her original name was Yin Zaixi, and she was beaten more often than eating, and was adopted after the death of her biological father. On the day of his father's death, Yin Jae-hee is said to have escaped from the house after being beaten, but the day of his father's death, there was no memory for six months before. Liu Xiuyue kept running in her dream, and met K-personality. After Liu Xiuyue woke up, she was always wondering why K appeared there. Looking at the psychiatrist next to him, Liu Xiuyue felt that he was completely different from the psychiatrist he saw in Dream Protection.
Personality K appeared in his passenger seat, and Liu Xiuyue asked him about the memories he had lost when he was a child. Personality K pretended to be silly and deliberately changed the subject. A girl with apathetic eyes went to the police station and said that she seemed to have killed her father, and then fainted and dropped a pack of eyeball drugs from her. This incident soon caused a lot of trouble in the society. Guo Fengbi said that Li Xiqian would be transferred to support the anti-corruption department in the near future. Liu Xiuyue must find out about eyeball drugs because this is a mess between him and Li Xiqian. Liu Xiuyue and Li Xiqian went out to investigate a murder case. Personality found that the atmosphere between Liu Xiuyue and Li Xiqian was strange.
Personality asked Liu Xiuyue if something happened with Li Xiqian that night. Of course Liu Xiuyue didn't dare to let him know that he kissed Li Xiqian. The deceased in this case was named Bai Zhenghe, an old acquaintance of Liu Xiuyue. When Bai Zhenghe was still in the police force, his daughter Bai Rongzhu provided Liu Xiuyue with account evidence, hoping to take Bai Zhenghe into prison. But after Liu Xiuyue investigated, only Bai Bai Zhenghe was punished by removal. After that, Bai Rongzhu was repeatedly tortured and killed Bai Zhenghe by mistake and reported to the police station. Liu Xiuyue felt ashamed and took the initiative to find lawyer Nan Enshuo, hoping that he could defend Bai Rongzhu. Li Xiqian had the same idea as him. Not long after Liu Xiuyue arrived, she also came to Nan Enshuo's law firm.
Shen Zhuxuan, a consultant at the Conservation Institute, called Liu Xiuyue and wanted to ask him for consultation tomorrow morning. Liu Xiuyue was too busy recently and refused. Investigations by Wu Jingtai and Liang Zaishan found that Bai Rongzhu’s computer contained a video of her killing Bai Zhenghe. It seemed that the video was going to be sent to someone. The police were tracking the IP address. Another bad news came. Bai Rongzhu committed suicide by cutting his wrist and jumping out of the window. After being rescued, he lay on the hospital bed. This abnormal behavior made Liu Xiuyue think that there might be a problem with her spirit, so she took the video content to go to the psychologist and asked him to look at it for help. The clues provided by the psychiatrist are very useful, Bai Rongzhu may be manipulated to kill.
Liu Xiuyue went to the school to consult a teacher and learned that Bai Rongzhu had ran away from home with a close classmate Gao Jiaying before. Liu Xiuyue went to Bai Rongzhu's classmates again, and found that Bai Rongzhu had been taken by the teacher to the Dream Sanctuary, where he received psychological treatment from a counselor. The results of Li Xiqian and Liang Zaishan's investigations are also related to Shen Zhuxuan. Liu Xiuyue went to Shen Zhuxuan impulsively, but didn't find any clues. Shen Zhuxuan was either excellent acting, or the whole thing was really a coincidence. Bai Rongzhu had regained consciousness, Liu Xiuyue wanted to ask something from her, but finally returned to no avail. Strangely, Bai Rongzhu once again asked what number it was today. Liu Xiuyue was anxious and did not find her strange.
Liu Xiuyue asked her brother and mother where they found him before, and then he went to that place, hallucinated, and entered a short dream. He wanted to open the door number 1002, but was stopped by K desperately. Bai Rongzhu ran away from the hospital, went to the protection center to find Shen Zhuyu and injured him. Since he was found to be sent to the hospital in time, Shen Zhuyu was not a serious problem. This incident allowed Liu Xiuyue to lower his suspicion of Shen Zhuyu. Liu Xiuyue saw an address in Gaojindong on Shen Zhuxuan's computer. He intuitively thought that Bai Rongzhu was there and drove away immediately. Bai Rongzhu was really there. After she said something inexplicable, she asked Liu Xiuyue what number it was today. After Liu Xiuyue answered, Bai Rongzhu quickly committed suicide.
After Shen Zhuyu was discharged from the hospital, Liu Xiuyue completely relaxed his vigilance and told him that he suspected that someone had used Bai Rongzhu to stimulate him. The real target was Liu Xiuyue herself. Shen Zhuxuan expressed that he was willing to help him if Liu Xiuyue needed help. Wu Jingtai found out Bai Rongzhu's dark web account and password. As soon as Liu Xiuyue boarded, someone sent him a message, and the other party actually knew his original name printed on Xixi.
