Ok, I've seen it so many times what it's obvious the only possible rating of my part is 10. It's just that the drama has an intense, dark and profoundly touching charm. There are many few Korean dramas with such a captivating melodramatic plot and equally few cases of such a chemistry as Ji Sung's and Hwang Jung Eum (fortunately, both of them reunited in "Kill Me Heal Me" and I couldn't say where they were better, as they really managed to play absolutely different characters with an amazing naturalism).
I love the aesthetics of painful beauty laying in the relationship of the leads, an interesting development of the characters and another wonderful feature of this drama: the supporting plot disgorged into the integrity of the drama with an absolute naturalness. There are a lot of brilliant dramatic scenes and somehow one can admire it as a good cocktail.
