I did not understand the ending where Yeon was reborn (as a human) in less than six months time! It kinda felt unreal and unconvincing. But the rest of the story was awesome and I liked every bit. Rang dying was probably the stupidest decision ever made by the storywriters and his sacrifice was not felt by his people as much as Yeon's did. It was like Rang's life was not even important for them. He was in fact my favorite character and it broke my heart to end it without him. The last part where Yeon slices his umbrella again and goldens his eyes was so damn satisfying! I watched that scene over a million times! I'm totally waiting for the second season. And I hope I won't be disappointed again!
