As the director of Yoojoong Constructions, Seo Jin hosts a violin recital where his wife performs in order to enhance the image of the company. However, the concert hall turns into chaos as their daughter Da Bin goes missing. Meanwhile, Ae Ri takes her mom to the hospital for surgery after getting a call that they have found a heart donor for her mom.

While Seo Jin hands out flyers to find his missing daughter, he gets a phone call from the kidnapper. Meanwhile, after Ae Ri’s mom goes to the hospital for the transplant surgery, she hears devastating news from her doctor that her mom’s condition is too bad to have heart transplant surgery and the donated heart will go to the next person on the list.

When Ae Ri goes back to the hospital, she finds that her mom is gone. Meanwhile, Seo Jin realizes that he is living a month ahead of Ae Ri. In order to save his wife and daughter, Seo Jin calls Ae Ri to tell the truth, but Ae Ri doesn’t believe Seo Jin.

Ae Ri asks Seo Jin to prove himself being in the future. He shares the winning numbers of the lottery, about her murder of Geon Wook, and in return asks her a favor. As unbelievable as it may seem, Ae Ri slowly starts trusting Seo Jin and visits his office in her time as he requested.

Seo Jin receives a call from the police that the culprit has been caught. When he rushes to the police station, he finds out that it was the very man who was protesting alone in the lobby of Yujung Constructions. Although it’s too late to save Da Bin, he believes he can still save her.

For a minute over the phone, Seo Jin informs Ae Ri of the name of the kidnapper and asks for help. While helping Seo Jin with the matter, Ae Ri receives a call from the hospital regarding her mother’s belongings. At the hospital, she finds out how Kim Jin Ho is also related to her mother’s disappearance.

When Ae Ri knocks on Kim Jin Ho’s door, Jin Ho panics and tries to force her into the house. That’s when Geon Wook shows up to save her, and the two start running away. After the incident, Ae Ri updates Seo Jin about the happening and tries to find the reason why she was chased.

Without knowing that someone close to him is hindering his efforts to bring back his family, Seo Jin desperately waits for Ae Ri’s phone call. At the same time, being unsure of the person who chased her at Jin Ho’s place, Ae Ri follows whatever lead she has acquired so far.

Although Seo Jin realizes that there must be more people involved in the kidnapping of his daughter, he still needs more information to be certain. Meanwhile, it turns out Hyun Chae was having an affair. While talking to Jin Ho, Ae Ri finds out about how her father met his death.

Seo Jin finally gets a phone call from Ae Ri. When he finds out that one of his close people tried to kill Ae Ri a while ago, he decides to persuade Jin Ho into helping him. However, Seo Jin doesn’t have a clue who else is involved in this matter.
