I don't care what others say. This drama is one of the best fantasy romance drama I have ever watched. Time travelling dramas can sometimes be confusing and "unrealistic". However, this drama did not have miracles or coincidences, but purely and not hesitant to use "time traveling" as a tool to construct the story. Every tiny scenes are connected to each other, and greatly affected the closing episodes.

The story had some unique initial settings, like an accident, a rapid marriage, and taking advantage of time travelling. They distinguished present and non-present scenes by using separate screen sizes, and brought up stuff like "future" products and lottery ticket digits, which are things one would probably do when you have the ability. I was a bit surprised about the rapid-yet-they-broke-up-once-marriage, but thanks to that, I think the drama was able to fit in 16 episodes, which was a perfect fit.

Casts and characters were awesome. Personally I loved the character Ma Rin, for her strong, understanding, and honest yet clumsy character. Doing everything she can with her power, but sometimes being clingy towards So Joon was just cute to watch. I really wished So Joon and Doo Shik were a bit more honest towards others.

The music had a perfect match for every scene, from a sweet, loving scene to an intense, sweating scene.

I am planning to watch the drama again, cause I want to remember details in every scene (like the train accident scene), and was also relaxing to watch. I think people can discuss things like fate and future after watching it.
