Liu Xiaoye, who was raped, sat quietly in the ward observing a snail. Shen Yi saw her in a white coat as a doctor.Liu Xiaoye thought Shen Yi was going to examine her, but Shen Yi just talked to her about snails.When Shen Yi came out of the ward, he already had the answer in his mind. Then Xiao Liu relayed Liu Xiaoye's description of the rapist to Shen Yi. Shen Yi drew many facial features based on the description.Xiao Liu couldn't understand Shen Yi's thoughts. Shen Yi said that many of Liu Xiaoye's observations came from perception, focusing on details and physical dimensions, so under the influence of hallucinogens, her descriptions would be more vague.Xiao Liu saw that these facial features had many connections in perspective. Shen Yi asked her to classify these facial features. In the end, the two pieced together three incomplete faces and found that Liu Xiaoye's encounter was probably a round of rape.With Shen Yi's encouragement, Xiao Liu picked up the paintbrush and completed the three portraits based on skull anatomy.When teaching Xiao Liu portraits, Shen Yi remembered his first painting teacher, Xu Yiduo.

The young Shen Yi was graffitiing on the street with oil paint. After seeing it, Xu Yiduo offered to teach Shen Yi how to draw. Shen Yi felt that learning to paint was not free, but Xu Yiduo said that he could bring Shen Yi real freedom.Xu Yiduo taught Shen Yi the painting techniques step by step and led him to feel the vitality of color. Therefore, Shen Yi had deep feelings for Xu Yiduo.

Based on the portrait drawn by Xiao Liu, Director Hu found three male students who were in the same school as Liu Xiaoye. Under interrogation, the three of them explained the process of their execution.Liu Xiaoye, who was living alone, was targeted by three people who had planned it for a long time. After the party that day, the three people took away the drunk Liu Xiaoye and gave her obedient water. Then they conducted a round of questioning. After the crime, the three peopleAnd the traces of the scene were removed with purpose.

Director Hu found that the portraits of these three people were missing something compared to the original three-eyed portrait. Shen Yi also noticed this and discovered the shape of a butterfly by erasing the facial features of the portrait.This is a portrayal of Liu Xiaoye's memory. Shen Yi wanted Liu Xiaoye to see it. Liu Xiaoye's mother looked at the butterfly and recalled the past many years ago.

Liu's mother was busy with work and could not pick up Liu Xiaoye from school on time, so she enrolled the young Liu Xiaoye in an interest class.Liu Xiaoye was molested by a male teacher while observing butterflies in a hobby class. Liu's mother was afraid that this incident would ruin Liu Xiaoye's reputation, so she did not make any announcement.

In order to untie Liu Xiaoye's knot and prevent more girls from being poisoned, Shen Yi persuaded Liu's mother to cooperate with him in investigating the matter.Shen Yi found the male teacher and brought him to justice. He also returned the butterfly specimens collected by the male teacher to nature. Perhaps in this way, those injured souls would be healed.

Xu Yiduo, Shen Yi's first teacher in painting, went to the police station to find him. Du Cheng asked Xu Yiduo to go to the reception room to wait for Shen Yi who was out. Xu Yiduo asked to see Shen Yi's paintings.Shen Yi is the most outstanding and talented student Xu Yiduo has ever taught, so Xu Yiduo feels sorry for Shen Yi giving up art and painting. He wants Shen Yi to become an artist instead of working in the police station.A portrait artist.Du Cheng bluntly said that Shen Yi was not an ordinary portrait artist because he could see people's hearts through their appearance, and he had made significant contributions in several previous cases.Du Cheng knew that Shen Yi loved the police profession, and he advised Xu Yiduo to respect Shen Yi's choice.

After learning that Xu Yiduo had come, Shen Yi called Xu Yiduo, but the news he received was that Xu Yiduo and his wife drowned at the beach.After He Rongyue's autopsy, it was confirmed that Xu Yiduo and his wife committed suicide. Shen Yi, who was extremely grieved, could not accept this fact when he looked at Xu Yiduo's body.

According to custom, Shen Yi found the key under the flower basin at the door of Xu Yi's house, and Ducheng and Shen Yi walked in together.Looking at everything familiar in front of him, Shen Yi remembered the care and concern that Xu Yiduo and his wife gave him like a son.Shen Yi saw the paintings of his childhood in the studio, and also saw a painting that he had burned seven years ago.
