This is one of the most well-written dramas I have ever seen! Although not so much for the ending, it managed to keep me on my toes for 16 hours straight! Almost everything was well written. The plot, cinematography, seasoned casts - especially the two male/female leads - simply put: awesome, although it is not without flaws. It's been a while since I can actually feel the thrill of post-kdrama-marathon watching, yet I did after completing this drama. I was never a fan of melodrama, yet this drama grabbed my attention down to the last episode - except for the last 30 minutes. I will definitely look for this writer's work again.
