The actors and actresses all did well in this drama. I just had a problem with the storyline. I don't know where the writers got their idea to write this script. I mean the main lead, Song Hye Kyo character Dong Eun was very cunning and slick to avenge her family's murder. That part of the storyline I did like. The part that bothered me was that the police didn't believe anything she said when that murder happened. It reminded me of the Law Enforcement officers in the United States, most don't believe what the Black and Brown people have to say. I learned that through experience. In the storyline, if the investigating officers believed her as a victim, she wouldn't have gone through all the sneaky and cunning ways to get revenge. The writers did a great job in writing Dong Eun's schemes. What I did get out of this storyline is a Mother will do anything for her children. I loved the house of Choi Kang Ho played by Lee Do Hyung.
