Most Tragic Character (tied with Bidam [Seondeok]): Kim Yoon Woo (Ryang Eum)
Most Inspiring Support Role: Choi Mu Seong (Gu Yang Cheon)
Most Supportive Friend: Ahn Eun Jin (Kyung Eun Ae)

Honorable Mentions:
Most Delusional/Pathetic Character: Moon Sung Geun (Lee Yeon Hyeon's ... spoiler)

Best Ending Ever: My Dearest (Part 2)

Cannot recommend this drama highly enough.
You have to watch it to believe it. I will never forget it.
Also, cinematography to die for.
