For me, the first TV series that Song Hoon suited very well. Maybe he has just matured with age and as an actor, but he entertained me here. Apart from him, I didn't know most of the actors. The casting for negative characters was excellent. Stepmother played her role awesome. The main female character was sympathetic. The transformation from a "gray mouse" and a poor woman to a woman seeking revenge was great. The lies, fakes, exploits, insults...etc. The concept of the accident, return in time and the fateful meeting/love was super contrived. Although, on the Big Day, I expected it to be something more to explain: the sign on the hands and why they had it. And the screenwriters were more daring with the romantic scenes. They were very beautiful.
