I so want this to have a happy ending! Why are Korean dramas usually so sad? Is it han?

I'm devastated. I loved every character in this drama. it was gripping from the very first episode. I couldn't stop watching it. It was very well crafted. The acting was great and filming was beautiful. I guess the thing that I really appreciated about this drama was that the characters were psychologically complex. Too often in Korean Dramas the characters are one dimensional, they are either good or bad, not so in Snow Queen. All of the characters had a very compassionate portrayal, I might not have agreed with someone, but I could understand why they were doing what they were doing. They all seemed caught up in events way beyond their control. It was just so sad. I haven't cried this much in a while.
