Episode 3 recap: Mysterious Observer.
Xiao Yi discovered wounds on Luo Yu Tong's neck and hands, suspecting domestic violence by Luo Hai. Xiao Yi questioned the neighbors, who only knew that they often had disputes but were unaware of the specific details. Xiao Yi went to the hospital to see Luo Dui, and Liang Dong Ni was also surprised, thinking that Xiao Yi wouldn't come.
Liang Dong Ni mentioned that numbers appeared at the crime scenes of both the Yang Ting case and the explosion case, which she found strange. However, since the cases had been transferred to other teams, she didn't have any videos at the moment. She found a small video uploaded by a netizen online and showed it to Xiao Yi. In the video, Xiao Yi saw the taxi they previously rode in, and the driver seemed very suspicious.
Xiao Yi escorted Liang Dong Ni home, but their car tire suddenly went flat. It reminded Xiao Yi about the car tire tracks at the abandoned building and Luo Hai's car tire. Xiao Yi noticed that Luo Hai's car tire didn't match the tire tracks at the crime scene, suggesting that he had changed the tires.
Liang Dong Ni informed Xiao Yi that she found records of a domestic violence case involving Luo Hai that was mediated by the police station three years ago. Xiao Yi speculated that the reason Zhang Liang was harassing Luo Yu Tong was likely because he had recorded Luo Hai committing murder and was using it to threaten Luo Yu Tong.
Bai Zhe monitored the actions of the Ma family, and Ma Ye said they would take care of that person. Bai Zhe drove to the dock and saw people moving things, including one particularly heavy box. The workers were discussing what was inside. The boss told them not to worry about it and to focus on their own work.
Xiao Yi went to the clothing factory where Luo Yu Tong worked to find her. Luo Yu Tong denied any connection between Zhang Liang's harassment and her father. Xiao Yi questioned other colleagues and learned that Luo Yu Tong stayed at home on March 1st and March 7th because she had days off, so she remembered those two days particularly well.
Dou Zi Lin went to find Luo Hai and informed him about Zhang Liang's harassment of Luo Yu Tong, urging him to pay attention to his daughter's safety. As expected, Luo Hai intended to kill Zhang Liang. However, it was all arranged by Xiao Yi's team, and the person posing as Zhang Liang was Dou Zi Lin.
Now, with solid evidence, Luo Hai was taken for questioning. Although Luo Hai denied committing murder, Xiao Yi had obtained a search warrant and found a bloodied axe and old tires in Luo Hai's house. The old tires had Luo Hai's fingerprints on them and matched the tire tracks at the crime scene.
Luo Hai confessed to killing Wang Su Hua and Feng Ying. He dismembered their bodies and packed them into a suitcase, which he then concealed in a food cart and brought to the abandoned building. As for cutting off Feng Ying's hands, it was because the body was too rigid to fit into the suitcase. Luo Hai admitted that he killed them because Wang Su Hua, despite being mute, was very noisy, and Feng Ying was a bully who feared the strong and looked cute when she was silenced. Thus, he violated them after their deaths.
Xiao Yi asked Luo Hai if he raped Luo Yu Tong, which would explain her deep hatred towards him. Luo Hai confessed to it. Xiao Yi took Luo Hai to identify the crime scene and even found a dagger in the woods. Xiao Yi sensed something strange because Feng Ying's hands had not been found yet. If Luo Hai killed Wang Su Hua and Feng Ying as substitutes for Luo Yu Tong, it would be contradictory for him to rape Luo Yu Tong. If he did rape Luo Yu Tong, there would be no need for substitutes.
Xiao Yi believed that Luo Hai's murders were not random, considering the deep connections between the victims and the kindergarten. There might be a reason for Luo Hai to seek revenge against them. Xiao Yi returned to the kindergarten to inquire further and learned that they had indeed quarreled before. Luo Xiao Man was pushed down the stairs by Wang Su Hua's grandson, but Feng Ying sided with Wang Su Hua's grandson, and the matter was eventually dropped.
I feel the most heartbroken for Qu Yuan Yuan. She lost her life due to the sinister intentions of her manager, her own brother, and the shopkeeper. Her fate should not have taken such a tragic turn.
If the manager hadn't been obsessed with work and insisted on keeping her under constant surveillance, based on the actress's freedom to sign contracts independently, there wouldn't have been the subsequent retaliation and blackmail from the shopkeeper, nor the regrettable accidental killing by her brother.
