To be honest, this is my most solid asian drama ever. I mean, it takes the lead from all my kdrama watches but the ending was left too open. From the characters, to the dialogues and the story, oh my goodness! I was drawn into a rollercoaster of emotions to the extent that i couldn't sleep until i saw the next episode. The writers did a fine job but spoiled things at the end. It felt like they were confused at how to end such a brilliant masterpiece. I'd rewatch if the ending was better. In all, I love love love it.
P.S He Han is my dream ? guy
