Since I heard the hong sisters were going to make a drama with Gong Yoo and Lee Min-Jung, I was like totally happy. I'm a big fan of these sisters and I've seen most of their work. The fact thait there was going to be "magical things", the body switch and others, sounded really great to me as I was in a kind of "fantastic drama period" because of Rooftop prince, Queen in hyun's man.. After the first 4 episodes, I was kinda disappointed, I liked it, but I felt like something was missing which I always found in a Hong sisters' drama. And after watching the fifth episode, I began to really really like it. And it went on like that, I was waiting each episode like crazy and was totally addicted ! So I just finished it, I woke up at 7 a.m to see the last episode, I was really confused because everything happened really fast, I think in the context it was so hard to do a great ending as the viewers wanted, I can't come up with something that would make sense as an end ( even if the main subject of this drama doesn't make sense actually .. ). Anyway, I loved the actors, I'm a huge fan of Gong Yoo and I definitely know why, I also love Lee Min-Jung, she's just SO talented and pretty. I loved the character of her brother as well. Ahn Suk Hwan also has a role in Bridal Mask at the same time it's so impressive. I didn't like Suzy much before but she was so cute and funny here. I loved all the background music too. It's not the kind of drama I would watch again entirely but just a few scenes I liked. So at the moment I think you should watch it since it's part of the "new drama genre" but the drama itself sadly lost most of its essence in the last 4 episodes. It's not a must-watch but if you have time to spare and are looking for something to watch, it can be a good choice.
