In this image Nakyum looks surprised and it seems he's talking with someone, maybe with Mr. Kim. It could be Seungho but this image isn't colored, so we don't if the painter is surprised and afraid. (The author uses shades of purple to show emotions like fear and anger).
Another thing I notice is that Nakyum is wearing a robe. So either he's using another robe of Seungho or Seungho bought him refined clothes.
The author posted a spoiler of a future chapter:
