This was a very cute and fun show to watch. A rom-com with a twist of science fiction kept me interested. It started a bit weirdly, but it improved over the show. Acting was very good, especially the main roles. Yoo Seung Ho (Kim Min Kyu) and Chae Soo Bin (Jo Ji Ah) did a really great job. Some scenes were in my opinion a bit exaggerated, I have to admit that I kinda liked this emotional rollercoaster though. The thing that I didn't like is the fact that it was sometimes cliche. Anyway, I would recommend it to anyone who loves rom-coms.
