This is a really good watch. I loved the storyline. I wished I could be a time traveler. I love this kind of storyline. It had me confused so I really had to go back and rewatch some of the episodes a few times. I get it now. Going back to the past and then going to the future had me so confused. After I figured it out, I was into the story. This is one of those dramas you can’t skip any episodes, or you will miss important parts… or ask yourself “why did this happen?” I really loved the two main actors/actresses, Lee Je Hoon (Yoo So Joon) and Shin Min Ah (Song Ma Rin) did very well. I felt sad for Song Ma Rin… I cried somewhat. I have to applaud Shin Min Ah for taking a hard role to play. If you see this drama, you will understand why I said it. I applaud the writers, directors, supporting actors/actresses, and everyone else. Thank you!
