Just can't hold it in anymore. I was not going to write a review around this but I have waited and anticipated for a long time to what this drama in full. The plot was brilliant and I was looking forward to enjoy watching this drama but the only thing that is a mistake in this drama is the lead actress Han Hyo Joo! Such a poor performance! They should have casted a different actress. She does not know her character. In fact, I don't think she has a character in this drama. Her acting is poor, lousy and amatuerish. I wish they casted a different lead actress who had the passion to bring life into the leading lady.
