Life Goes On
At a crucial basketball game in which he must prove his skills in front of Hanguk University scout, Dae Young chooses what’s best for both him and Da Jung. After 18 years, he’s on the verge of getting divorced. Just before he’s about to give up, he hopes for a miracle. Believe it or not, he finds himself with the body of an 18-year-old kid.
About the Things That Made You Smile
As 18-year-old Hong Dae Young, Ko Woo Young realizes that his children are living a life that he wasn’t aware of, and he decides to encourage them as a friend. In the meantime, Da Jung goes through blind recruitment at JBC. While having a night out with Ae Rin, Da Jung comes across Choi Il Gwon, a high school friend. On their way back home, Da Jung sees Woo Young whose appearance seems to overlap with that of Dae Young’s.
A Story About Rain and You
Da Jung gets a phone call from JBC regarding the results of the open recruitment. Meanwhile, Woo Young picks a fight with Ja Sung when he just won’t stop bullying Si Woo. On her first day at JBC, the fact that she is married dissatisfies the higher ups, resulting in a clearly biased treatment towards Da Jung. Later on, Da Jung gets a chance for an interview with only a few minutes left before going live.
The Boy We Loved Back Then
At a team dinner with the baseball team, Ji Hoon requests the director to schedule Da Jung for his upcoming interview. Meanwhile, Si Ah is taken to a nearby hospital, which worries everyone around her, especially Woo Young. Ironically, Da Jung is again disappointed by Dae Young’s reaction to Si Ah’s condition. On top of it, Da Jung hates the fact that Dae Young is lying to her about his business trip to Busan.
First Loves Never Come True
Dae Young wants to know why Da Jung wants to get divorced. However, Dae Young can’t get the answer from her as Woo Young. Dae Young finds out that Il Gwon is seeing his first love, and he suspects that Il Gwon and Da Jung are having an affair. Meanwhile, Da Jung gets public attention with her interview video.
A Sincere Heart of Her Number 1 Fan
Dae Young is bothered by Ji Hoon who tries to get close to Da Jung. Da Jung’s divorce gets public, and she loses her programs due to public opinions. Ji Hoon takes Da Jung to the field to comfort her, and Il Gwon gives up on seducing Da Jung. Meanwhile, Dae Young finds out that his father has been taking care of his children and Da Jung.
Someone Who Gives Courage to Me
When Deok Jin envies the fact that Dae Young has become young again, Woo Young carelessly blurts out his true identity. Ae Rin, who happens to be right next to them while waiting for Da Jung, hears their conversation. Meanwhile, Il Gwon asks Da Jung for an inappropriate favour as Si Woo’s basketball coach. Thanks to Woo Young’s advice, Da Jung does the right thing but gets caught doing something that might provoke Il Gwon.
The Story Only I Didn't Know
While Woo Young is unsure of the conversation between Da Jung and Il Gwon, he is worried that Da Jung might have found out his true identity. Meanwhile, Da Jung is shocked at what she heard about Dae Young. When Dae Young comes across his father at his mother’s grave, he invites him to his basketball game. After the game, Dae Young pours his heart out.
