This is a pure unadulterated trash drama- period.
The story starts off strong enough (the first 2 episodes at least) that you can't help but be excited about it. The premise of reincarnation is nothing new but the synopsis made it intriguing. The wheels fall off fairly early on and if you decide to continue/ complete this drama be prepared for a nice long train wreck. It's a fantasy story-line but that doesn't give it an excuse to be incoherent.
The cast did the best with what they were given. Lee Soo Hyuk- came back better than ever and my gripe is that he deserves a better script than this (he nailed the crap outta this role). Jin Se Jeon- my first drama with her and I wasn't impressed. Again though I'm blaming the writing for her character being wishy-washy and all damsel in distress-y. Jang Ki Yong- I feel he is being type cast at this point as the strong, deadly, silent type. Not saying that's bad but... I just want to see him do more than just stare beautifully into the camera.
The music was lovely and I'll for sure be checking out the OST's to add to my chillax playlist.
Overall this drama did not meet my expectations in being a great mystery drama but instead became a top choice in my trash drama list. I'm kinda pissed off I wasted my time with this but at the same time I'm glad I watched it, so with that I would recommend it.
