Ji Sun Woo, together with Dr. Kim, met Chairman Yeo in a private dinner. Her plan to keep Tae Oh and her side not as suspect failed because Hyun Seo reported to the police as a witness of In Kyu's death.
The detective waited for Tae Oh's statement about the alleged complaint, but he kept silent. However, everyone in the station was shocked as Sun Woo arrived and faced the detective to save Tae Oh from police interrogation. She stood as a witness that Tae Oh was with her during In Kyu fall from the rooftop. She took out Tae Oh's wedding ring and surrendered it to the police. She made it as a proof that Tae Oh is not the murderer. Hyun Seo tried to convince the detective that it's not the real story, but Sun Woo stopped her. Sun Woo told her that it was only her assumption.
Tae Oh realized how Sun Woo valued him as Joon Young's father. She never abandons him when he needs someone to save him. Da Kyung and Chairman Yeo decided not to answer his call when Tae Oh looked for help at the police station. He was disappointed and shouted at Da Kyung as she neglected him. The video that Chairman Yeo kept from the station shows the almost exact time that In Kyu fell from the rooftop and Tae Oh went inside the basement. The video could have saved him, but he took it.
Sun Woo advised Hyun Seo that the case is over and it proves as In Kyu's suicide. She warned Sun Woo that if she keeps protecting Tae Oh and pities him, she will end up losing herself.
Joon Young got bullied by his classmates as Hae Kang shared the malicious rumor that Sun Woo had an affair with In Kyu. Joon Young almost caught up a fight with Hae Kang, but the teacher came in and stopped them. Sun Woo found what bothered Joon Young at school, as Noh-eul told her about the circulating rumors.
The next day, Sun Woo was furious to see Hae Kang's mother and warned her to stop the false rumors. Joon Young knew what she did and got mad for getting back at his classmate's mother. The school was once again surrounded by rumors after what Sun Woo did.
Da Kyung convinced Joon Young to live with them. She mentioned that it would help him and his mother to start a new life. Should Joon Young live with Tae Oh, this would give Sun Woo the chance to live a new life and leave Gosan. Joon Young accepted her offer and asked his father to help him pick up his clothes.
Tae Oh called Sun Woo to meet them in her place. Joon Young packed his clothes and informed his mother he would start to live with his father. Sun Woo felt crushed deep inside, seeing Joon Young leave the house. Tae Oh told her that he would try to talk to Joon Young and stay with him for a few days only.
Da Kyung welcomed Joon Young at her house. She sees Tae Oh is happy to have his son with him.
The next day, Sun Woo goes to work, trying to stay calm while she calls and talks to Joon Young. Dr. Kim asked her out, but she started to decline to stay away from him. She strolled at the mall to keep her mind off as she misses her son. In the clothing department, she saw Joon Young walking. She followed him and saw Tae Oh, Da Kyung, their daughter, and Joon Young from a distance. They look like a happy family together. She felt a deep pain in her heart that a family is what Joon Young needs, which she can't give for now.
Sun Woo crossed her mind to check on new hospitals to work with outside Gosan. She thought of plans to leave the city and start a life away on her own. Ye Rim got her divorced approved, and she will move to Seoul anytime soon. She advised Sun Woo to let go and have a good break away from all the hassles in Gosan.
The whole day, she never received any reply message from Joon Young. Sun Woo came to realize that Joon Young might want to forget her and stay with his father. She packed all Joon Young clothes and other personal stuff to send to him.
Tae Oh arrived home and saw university books overseas for new enrollees. Da Kyung kept it from him. He yelled at Da Kyung as she entered their bedroom. She has plans to enroll Joon Young abroad to live a peaceful environment and live a life away from his divorced parents.
Sun Woo message Tae Oh and asked him to pick up Joon Young's things. As Tae Oh arrived in her house, they had another heated argument about him and their past. Sun Woo cried hearing Tae Oh's words and she tried to hit him, but Tae Oh held her arms and they felt a sense of passion looking at each other's eyes. Their body ignited as their lips sealed, leading them into a passionate night in bed.
