Factual error: Ae-sun is shown carrying a bag filled with gold bars with virtually no struggle. Gold bars 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)
Episode #1.9 - S1-E9
Other mistake: The blood stain on Se-hun's collar shown when Eugene slices his neck doesn't seem possible. Within just two seconds of the side of his neck being slit, his collar appears to have been covered in blood, indicating that he must be bleeding at an incredibly fast rate, but for the rest of the scene, his neck never continues to bleed. (00:56:03)

The baby is heard crying, but there is a brief moment where she shakes her to calm him down, and we can see the baby's eyes when she does so.
