This drama had severe mood swings as it progressed. Kim Tae Hee and Joo Won portrayed such a painful, understanding, but loving relationship that I really enjoyed. The FL is what you call a badass, emphasize on the "bad". Kim Tae Hee truly deserves her recognition as a "national beauty" and is a charismatic actress. Joo Won is just absolutely magnificent in his portrayal of the many emotions of the ML. As the show furthered, our FL became engrossed in revenge to the point I was questioning if she was gonna die in the end or not. The ending was incredibly rushed, especially in the last 10 minutes of the show.
