Success of vitamin (Korean edition)

The pacing is relentless, but I wondered how much thought went into giving characters depth amidst all the thrills. Did that come naturally or was it a conscious choice?

The surprises kept me on edge, but I’m curious if the clues were subtly woven in or if the twists were more of a shock factor. What was the experience like for others?

The geopolitical backdrop adds to the tension, and I wonder what motivated the author to choose this specific era and locations for the story’s events.
