Watch Alone in Love
Sometimes you do find love, marry it and live with it, but still not realize that it was there all along, so you end up divorcing. Alone in Love is about a couple in that very scenario. After an intense attraction to each other, Eun-Ho and Dong-Jin get to know one another, marry and divorce. Believing that is was the right step to take, the couple realizes that they can't move on from each other.
If destiny does exist, it's easy to argue that Eun-Ho and Dong-Jin's love for each other is destined, but will they realize it too late.
