After understanding Seol yoon’s intentions, Soo-hyun focuses on treating her family better and takes Suh’s mother and hers for oriental treatment. There, her mother-in-law asks Su-ho why he likes Soo-hyun so much to which he tells her that she is the one who liked Soo hyun more than she liked him. (She was actually fond of Soo hyun)

The psychiatrist reveals the truth and apologizes for her behavior, but Soo-hyun makes her realize the drastic situation Seol yoon is in which he needs to be freed from. She then takes the information of the real fire victim and makes her way to save another life. She meets him and tells him to change his life so that his parents can live through him. He seem hostile at first but he begins to look saddened after Soo hyun relays her own tragic experiences to him because she sought revenge.
She then hands over some contact information and later calls the psychiatrist to let her know that he will be resuming treatment soon. Meanwhile, Seol yoon is asked to deliver a package to Kim Joon from Hye-geum. He takes the package but hands it over to his friend who quickly finds the pen drive hidden in it and transfers the information from it.
He then delivers the package and confesses that he is the one who sent the pictures to Soo-hyun and her mother. Kim Joon is convinced that he is someone on the road to revenge while Seol yoon assures him that he will get revenge on everyone who ruined his parent’s lives. Elsewhere, Su-ho’s friend hands him a picture of Seol yoon with Soo-hyun which makes Su-ho curious.
Suho later questions Soo hyun at home and she tells him that Seol hyun is the one she handed her diary over to. He then tells her to stay away from him and later secretly checks on information about the fire victim.
The next day, Soo-hyun visits Tae-ho and comes across the political rally held by Kim Joon. She meets Tae-ho and tries to get more information about Seol yoon. He then reveals that Seol yoon’s mother has been moved into the VIP ward and it is none other than Kim Joon who did this. Following this visit, Soo-hyun follows Kim Joon surprised to see that they are seen going the same way. They stop at her neighborhood and Soo-hyun is shocked to see Kim Joon entering Hye-geum’s house.
Inside the house, Kim Joon hugs Hye-geum and tells her to leave the country as soon as possible as he cannot let anything block his way to political success.
Meanwhile, another political rival is out of the game which creates issues for Su-ho who then decides to bring Kim Joon on his show. The next day, Su-ho and Soo-hyun notice someone in front of his car. The stranger asks them for the dashcam footage from Su-ho’s car which can be helpful to him after he got into an accident. Su-ho hands it over to Soo-hyun and asks her to help him out. Later, Soo-hyun checks the day’s footage mentioned by the man.
She gets nothing but can’t continue watching because she gets attracted by the footage towards the end. Soo-hyun tries to check it out but a commotion outside catches her attention and she rushes out. It is Hye-geum’s son who is having a seizure and Soo-hyun helps him out until Hye-geum arrives. The two then take the boy back home and Soo-hyun is attracted by a picture which was taken on the day mentioned in the picture sent by Seol yoon.
Hye-geum notices what she is looking at and confesses that she is not the woman in the picture but tool the blame because Su-ho is helping her and her son and had asked her for this favour. She tells her that Su-ho told her that he is trying to save Soo-hyun by not letting her know who is the woman in the picture.
However, doubts are arising in Soo-hyun’s head as she thinks of the worst possible case. Elsewhere, Su-ho finds out that Kim Joon is ready to be on his show and receives a package sent by his friend. Upon opening it, his doubts come true as Seol yoon’s real identity is now known to him as well.
Meanwhile, Seol yoon has something new planned for Soo-hyun, who at the moment understands that Seol yoon has tried to show her something. However, she takes the disk and goes to Yu-ri’s boutique where she calms herself to check the video that has been on her mind since earlier.
While she checks the video, a face enters Yu-ri’s shop which brings back her worst nightmares- her birth mother. While Yu-ri struggles with the woman, Soo-hyun gets up to check on the commotion but is stopped when she hears what Su-ho said to Yu-ri a few days back. He has confirmed that the woman in the picture is Yu-ri, which leaves Soo-hyun shattered.
As for Seol hyun, he smiles to himself as he sits beside the boutique building, happy that Soo hyun’s world is crumbling.
