I don't understand why this drama insn't more famous it was one of the best I've watched, you can't find kdramas this good nowadays. One of the best things about it is the acting of the main leads, So Ji Sub and Shin Hyun Joon are incredible actors, I've read that some of you think that the villains and Sun Woo were overacted but I don't think they were at all, they were very well played and the guy who plays Choi chi soo was amazing . I think koreans do very well with melodramas and I liked that this had a heartbreaking but closed ending. I admit it laked a bit of romance and I would have liked to see more chemistry and romantic moments between Cho in and Yeong Yi but I understand it isn't the main point of the drama since the poor guy goes through a roller-coaster of shocking events and founds his own family wants him dead while having done no harm to anyone.
