Episode #1.7 - S1-E7
Other mistake: When Tsuda and Yamada are in Hayashi's office, Hayashi takes out a sword and executes Yamada. Based on the length of the sword, and the distance between where Hayashi was standing and where Yamada was kneeling, there is no way the sword could have killed Yamada. Tsuda was in between the two and the sword wouldn't have been long enough to reach Yamada given how far apart he and Hayahshi were. (00:17:10)

Episode #1.9 - S1-E9
Continuity mistake: When Eugene stabs the sword through Se-hun's chair and slices the side of his neck, there is a blood stain on Se-hun's collar.

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)
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.

Then it is blowing in the wind again the shot after that. (00:01:45)
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)
