Before Soo-hyun arrived at the memorial service, Seon-yul had already gone through his mother’s phone and found a recording that left him shocked. It was the call recording from the day his father was killed by Soo-hyun and after hearing how harsh and unsympathetic his father was towards her plight, he finally understands the circumstances that led Soo-hyun to make that unfortunate choice.
Right then, Soo-hyun arrives and pays her respects to Seon-yul’s mother while promising her that she will take care of Seon-yul on her behalf. As she leaves from there, Seon-yul stops her and questions the reason for her arrival. Soo-hyun sees his state and tells him to contact her when he has finished grieving and leaves.
Seon-yul continues to grieve while Soo-hyun arrives home to see Su-ho who tells her that he is there to pick up some things. Meanwhile, Yu-ri reminisces about the days when she was happy with her sister and regrets her actions that ultimately broke their bond. The next day, Su-ho’s mother visits Soo hyun’s mother Go-eun who is aware of the reason why she has come to see her.
Go-eun makes it clear that she will not stop Soo-hyun if she proceeds with a divorce and tells Su ho’s mother that she would do the same if Soo-hyun were her daughter. Su-ho’s mother tells her that she would indeed tell Soo-hyun to get a divorce and while she has always loved Soo-hyun, she is Su-ho’s mother in the end.
She then leaves there but meets Soo-hyun outside and tells her to reconsider her relationship with Su-ho. Soo-hyun tells her that she will contact her when she has been able to put her feelings together. Soo-hyun then enters the restaurant and meets her mother. Elsewhere, Seon-yul finishes his mother’s burial and leaves the cemetery.
Kim Joon visits him, assuring him of his support and asks if his mother told him anything before she died. Seon-yul tells him that he wasn’t there during her final moments and Kim Joon brushes the topic aside (Suspicious) Seon-yul tells him that he wants to investigate his mother’s accident once again but doesn’t say much.
Kim Joon gets in his car to leave and comments on how Seon-yul is too stuck on his mother’s death. Meanwhile, Seon-yul is aware of something but quietly returns home upon which his friends show their concern for him. Seon-yul doesn’t say much and enters his home alone where he once again opens the recording he found in his mother’s phone. As he breaks down because of the truth in front of him, days and nights pass by while his friends try to help him out of his depressing condition.
Finally, one day Soo-hyun knocks on his door and Sen Yul opens his door surprised to see her. Soo-hyun tells him that she is aware of how he feels and that he should get himself together before she can pass on the information that she has on hand for him.
Seon-yul finally eats the food in front of him and tries to pick himself up once again. The next day, Soo-hyun takes her mother out to spend time together and finally at the end of the wonderful day, she confesses about Seon-yul’s identity. Go-eun cries for her daughter who had to bear the pain all alone again while Soo-hyun too breaks down in front of her mother.
Later, she tells Soo-hyun to not hate him too much as he too is in pain. With this, Go-eun falls asleep while Soo-hyun thinks of her mother’s words. Right then, she gets a call from Seon-yul and upon picking up the call she hears a familiar conversation. Seon-yul plays the recording he found in his mother’s phone and Soo-hyun is reminded of the moment she changed everything.
Seon-yul then tells her that he still cannot forgive her but is also aware that she must hate him and finds it hard to face him. Soo-hyun does not deny this and tells him that she had lost her child and spent 7 years in prison but when she realized that the man she killed also had a family, it was like a wake-up call to her.
Seon-yul tells her that he was aware of her situation, he too was in hell during that time, but he chose to ignore it and thought that getting his revenge on her would keep him alive. With this, he disconnects the call and once again bursts out in tears. The next day, Soo-hyun contacts the reporter who covered Eun-min’s accident and gets photos of the scene.
She then contacts a lawyer who specializes in traffic accidents and finds out more about the accident and how it can be brought up legally. Elsewhere, Seon-yul notices something in his house that seems out of place and looks around only to realize that someone has been to his house. He calls his friends and they confirm that no bug has been planted in his house, but starts wondering who spied on him.
Right then, his friend Soo-jin tells Seon-yul that his mother said something weird during her last moments and tells him what she said. Seon-yul is in shock and soon contacts Soo-hyun to let her know that he is ready to know what she has for him. Soo-hyun picks up the folder she has prepared for him and heads to meet him.
She tells him that his mother’s accident was planned and that the driver had been waiting for her for a long time. She then hands over the folder of documents that can aid him if she wants to go all the way. Seon-yul asks her why the driver did this and she tells him that he had been ordered to hit his mother.
He asks who ordered the man to do this and Seon-yul tells him that he knows the perpetrator; it is Kim Joon. She asks him why he works for Kim Joon when he is aware of the man’s actions and a flashback shows all the preparations Seon-yul has made to get his revenge on Kim Joon.
