This drama gave me major feels - ah, throughout the entire drama I had tears pouring out like crazy. It's a great drama. Story: I've seen a couple like this one already but each one is new to me. Past's entwined and future's entwined - the description reminded me of Beyond the Clouds (2014) which also stars Yoon Kye Sang as the lead in almost the same predicament - which is one of the reasons this intrigued me. Cast: I started this drama for Yoon Kye Sang and I have to say it was a good choice, he is a great actor that can really pull the emotions out of you. It was my first time seeing the leading lady though and it took me a couple of episodes for her to grow on me. There were a few episodes in the middle where I really hated the lead girl, she was so mean. The second leading characters were nice and there were only a few times I got mad at them. Music: Pure perfection <3 I love OST's like this one has <3 Really reminded me of Swallow the Sun's OST Re-watch value: 8/10 - I loved it and would watch it again sometime.
