In the cold winter, 36-year-old Wen Dongen (played by Song Hye Kyo) returned to Shiming again, and she was determined to start the road of revenge. She posted photos of her revenge target in the house, and imagined Park Yeon-jin (played by Park Ji-yeon) walking into the house countless times and seeing the expression on the wall full of photos. Since Wen Dongen was 20 years old, she has worked hard as a tutor to earn money. In order to observe Pu Yanzhen whom she hates more closely, she rented the house closest to Pu Yanzhen. Every time she walked to the top floor of the rooftop, she could see the opposite Pu Yanzhen A villa where the family lives.
In Wen Dongen's memory, in the summer of 2004, she was still a student. Because she had no family background, she was bullied by Park Yanzhen and her team at school. Li Sarah and Sun Mingwu took Wen Dongen to the gymnasium. Park Yanzhen asked her to help her on duty. Wen Dongen refused, but was violently attacked by Park Yanzhen. Wen Dongen took the initiative to call the police. Director Shen Yingjun had friendship with Pu Yanzhen's family, and the case was hastily closed.
Teacher Quan, the head teacher, was called to the police station as a guardian. Not only did he scold Wen Dongen, but he was also very enthusiastic about other people who violently attacked her. Park Yeon-jin's mother blamed her for this, saying that she couldn't even solve Moon Dong-eun who had nothing. Wen Dongen didn't dare to go home, the only house she rented was also found by Pu Yanzhen.
Wen Dongen was burned by the hair straightener. She came to the school infirmary and wanted to treat it with hydrogen peroxide. The doctor saw that her hands were covered with bruises and asked her who she was. This was not the first time she had discovered it. But when Wen Dongen hesitated, she heard the familiar bell of the infirmary. When the curtain was lifted, Pu Yanzhen appeared with her mobile phone, and she confidently said that she did it.
Park Yanzhen and others intensified. They not only bullied Wen Dongen at school, but also went to her short-term rental house, ravaged her hard-earned change, asked her to dance, and even burned her legs with a hair straightener. Wen Dongen, covered in scars all over his body, came to the school infirmary again, but the school doctor was told on the door that he had resigned and could not see a doctor for the time being. The hopeless Wen Dongen went outside, and the whole city was covered in snow, she cried and looked at the sky. Snowflakes fell on her scar, which seemed to relieve a little pain. In order not to hurt her whole body, she took off all her clothes and lay down in the snow, using snowflakes to numb the wound.
Wen Dongen figured it out, she decided to drop out, but in the reason for dropping out, she wrote down the names of five people including Park Yanzhen, and identified them as school violence. Teacher Quan, the class teacher, was worried that this reason would affect his performance. In addition, when Wen Dongen mentioned his son, Teacher Quan slapped Wen Dongen severely in the office in front of everyone, regardless of the eyes of the people around him.
In order to modify the reason for dropping out, Park Yeon-jin's mother bought Jung Mi-hee with 1 million won. After Zheng Meixi got the money, she quietly severed the mother-daughter relationship with Wen Dongen, signed a new reason for dropping out of school, and canceled Wen Dongen's short-term rental house. Desperate Wen Dongen wanted to jump into the river several times. After she dropped out of school, she went to work in a restaurant. The wounds on her body accompanied by menstrual pain made her unbearable sometimes, but she persisted, which gave her a new idea.
Park Yanzhen and others looked for new targets of violence. They continued to do evil in the gymnasium and bully other girls. Wen Dongen took the initiative to go to the gymnasium and declared war on Pu Yanzhen and others. Her future goal is Pu Yanzhen. Knowing that Pu Yanzhen's dream is to be a good wife and mother, the others couldn't help laughing.
In order to improve her academic qualifications, Wen Dongen entered a textile factory to work, but she studied day and night, and soon obtained a high school diploma and was admitted to a university. In the textile factory, Wen Dongen met Chengxi, a female tool, and the two became friends. Wen Dongen was admitted to the Normal University, and she was thinking about how to reunite with Park Yanzhen every day. She decided to start with the person Park Yanzhen cared about most. After graduating from university, Wen Dongen was successfully admitted to the establishment, and Park Yanzhen also married into a wealthy family, became a weather anchor, and gave birth to a lovely daughter, Park Yesol
