There's no doubt that this is one of the best K-dramas around. And there are many reviews that will say the same. But this review is my thought about it. And nothing more.
I loved the cast. They were great. Each and every one of them played their characters as perfect and real as they could. Hyung Bin & Ha ji won both are one of the most talented actors around. And they played there roles perfectly.
Specially in the body switching parts. Hyung Bin just stole the spot light for me at that moment. He was so funny. Specially his expressions. They were gold.
This is the only drama, I've so far with the most amazing OST. Each and every song had a reason. They were somehow part of the story. And they were so beautiful, that you just have to love it.
I loved the story. Well some of it. The only thing I didn't like was the switching. It wasn't necessary. It would had been an amazing drama even without. The switching - which most people were expecting, and it was funny - had little to none with story. In my eyes, it didn't do anything with the characters development.
Even saying that I loved the scenes. The actors were the reason.
And then the ending.
Overall it was an amazing drama. A great watch. It's full of fun stuff and moments. That's the reason it gets an overall 10 in my review and a place in my favorite drama list.
