So Joon chooses to be stabbed by Yong Jin to save Ma Rin taken hostage and goes to the future getting his wound treated. When So Joon comes to his senses after being trapped in a coma for two years, he finds out Ma Rin is already dead. He is determined to go back to the past to meet her, but he seems to lose his ability for time traveling. Can So Joon save Ma Rin again?

As Ma Rin is kidnapped by Yong Jin, So Joon comes up with a plan that will only save Ma Rin. He sends Doo Shik to save Ma Rin, and he heads to the station to face Yong Jin. Knowing what So Joon is up to, Ki Doong also brings police officers to the station and they were able to catch Yong Jin red handed. But what will happen to So Joon who is hurt?

Yong Jin sees So Joon vanishing into thin air while riding the subway. After that, Yong Jin goes to Ma Rin’s house and tells her what he saw. When he leaves, Ma Rin and So Joon talk about how there is no way he’d know how So Joon is a time traveler. Little do they know, Yong Jin is listening to their conversation over the bug he planted when he was at their house.

As So Joon promises Ma Rin that he will never travel back and forth the time, Ma Rin finds out that So Joon had actually been very helpful to Ki Doong while he traveled back and forth the time. Though Ma Rin doesn’t want So Joon to travel time anymore, she is a bit intrigued by the future items and news. Meanwhile, Yong Jin completely loses control over himself and falls deep into the mire.

Ma Rin packs her things and leaves So Joon to go stay at So Ri’s house. Although their relationship has taken a drastic turn, Ma Rin drops by So Joon’s house and waits for his calls as she believes they can reconcile. Despite that, So Joon chooses to be cold to her which makes him feel tortured.

So Joon still can’t seem to find the reason what really happened to Sung Kyu. As he tries finding out what really happened by going back and forth the future, Ma Rin wants him to stop because she is worried about him. But as So Joon continues, he learns that what really changed was his own fate.

It’s hard for Ma Rin to admit, but with the series of events that took place in the past, she has no choice but to accept the fact that her husband is a time traveler. Feeling compelled to tell Ma Rin a little bit about the future, So Joon tells her that something bad will happen in the near future and that he will do everything to stop it from taking place.

As Doo Shik tries to separate Yong Jin and So Joon, So Joon grows suspicious of Doo Shik’s strange behaviors. Thinking Doo Shik is up to something, So Joon travels time to find out horrible truth. In order to prevent from the horrible accident from happening, he decides to tell Ma Rin the truth about himself.
