Warning: A long review coming ahead. Read at your own risk. [Story] Quite unique story compared to the other time traveling dramas I've watched. At times this drama would confuse me as each episode progresses but it only made sense, well everything was explained in episode 15. So you've got a long way to go before you get there. No skipping! Every episode, I try to guess and make hypothesis in everything that's going on but in the end, the events they show us in the next episode were quite unexpected that it'll blow your mind. [Acting/Cast] I gave it an 8 out 10 because Shin Min Ah, my Queen. But I also love Lee Je Hoon, the time traveler expert since Signal. For me, there were fresh faces that I've only seen in this drama so far and I would love to see them in their future projects. Acting wise, it was good. Of course, Shin Min Ah and Lee Je Hoon are both amazing actors so I give them that. Even their chemistry was overflowing. That was actually very unexpected for me because I never imagined them to be paired up together. The other actors were also good and funny. Good job~ [Music] I've got nothing much to say about their music because it didn't appeal to me much except the last OST they played at the last scene of episode 16. That was nice but if I were to download it, I wouldn't. Don't get me wrong, I love listening to Korean dramas OST but I'll pass with this one. You can try listening to it, we all have different taste anyway. :)
