Despite all the bad reviews about this drama, I'm still excited to watch this because I'm a fan of Gong Yoo acting. And I think i'm right, Gong Yoo act so well in this movie. But somehow I found myself skipped a lot of scene when I watched this. After a lot of thought, this is my opinion : Act: 2 main actors doing a very good job in acting, but somehow the chemistry between them wasn't good enough. So if I watched them individually, their act is impressive but they re lacking chemistry. Thats what I thought. Music: actually, I didn't listen to it because I skipped a lot so....well...what can I say The biggest failure in this drama is the storyline I guess.... I think there's to much going on, to many people involved in the plot and almost everything wasn't well executed. about the marriage for example. I think the scenario actually can be 2 up to 3 different drama. I found myself liking it at the beginning, since it sweet, but I'm getting confused and boring after around episode 3. The main idea about the story was brilliant, and I like it (the main idea about switching soul) but to many twist in between and a lot of it wasn't well executed..so.. Still..I'm able to finished it, but I don't want to watch this drama ever again.
