After freezing still for a moment, Min Byung-Ho eventually shifted his eyes away from Hyun. He didn't recognize him. In truth, it would have been impossible to.
Back when they were all living in the capital and before Kim Jong-Seo died, Hyun had seen Byung-Ho once. Granted, it was from afar and the other man didn't turn his eyes to him, but it still gave Hyun the small chance of recognizing him now.
Byung-Ho, on the other hand, had never seen Hyun properly before, not even once. To be honest, it wasn't just Minister Min's son who was in the dark. Few were those who have had the chance to talk to Hyun or even see him from a distance.
