Continuity mistake: When Eugene and Ae-sin are talking on the ice at the start, there is an accessory attached to Ae-sin's hat that is being blown by the wind. After Ae-sin asks "who said such a thing" and Eugene replies "Some nobleman", the accessory on her hat is suddenly still and is not affected by the wind. Then it is blowing in the wind again the shot after that. (00:01:45)
Continuity mistake: When Seung-gu tells Ae-sin "Time has come for her to part ways with him", there is a close-up of her about to tear up. In this shot, strands of hair can be seen blowing across the side of her head. When it cuts to a wide shot, the strands of hair are suddenly blowing over her face. (00:23:08)
Factual error: Ae-sun is shown carrying a bag filled with gold bars with virtually no struggle. Gold bars, in real life, are heavy. And carrying around an entire bag filled with them, without struggling, would be extremely difficult to do. (00:08:44)
Other mistake: Chun-sik is standing next to a sweet stand talking with the vendor. Whilst he is saying "You know, I was quite skilled with swords back in my days", he is shown holding some bread, but he is not shown eating it nor is he shown taking a bite. The vendor then starts saying talking and Chun-sik still does not eat any of the bread, but then he is suddenly shown chewing, even though he never took a bite out of the bread. (00:07:15)
