I have read somewhere that fantasy is the ultimate genre to explore all those feelings and secrets of human heart and this show with Kim Eun Sook writing proved it. It was show about friendship, devotion, but mostly of love.
For a long time I have not enjoyed watching a show like this one and it will always hold a special place in my heart, thanks to a beautifully written love story between the main leads.
The main story is very interesting, with the theme of parallel worlds, devious villains, but what I loved the most is romance.
It has been a long time I have watched a romance K-Drama like this one, where the main theme is this epic, fantasy love story and what is the most important, the writing was not shy because of it, in contrary, I had a feeling I was basking in that glorious feeling of an epic love tale. The main characters were not fazed how they felt about each other, they were lucky, they met and fell in love and it felt like a touch of destiny and they were grateful for that. There were no love triangles, no crazy in laws, no annoying unbaised misunderstandings, just their unconditional love and it was so beautiful, that truthful simplicity of their feelings and their unflinching will to fight for their love.
The main actors Lee Min Ho and Kim Go Eun had an amazing chemistry and they portrayed their characters perfectly, their scenes were heart swooning and so lovely. I laughed and cried with them, which is always a good sign, that a show touched my heart. After this show I became a devoted Min Lee Ho fan. :)

The other characters with their stories, enchanting scenography and captivating OST were perfectly included in the main story, which resulted in one fulfilling K-drama viewing experience. :)
