After an extensive searching for Gun, the authorities finally apprehended Gun and his boss, Dongsoo Choi. However, before Dongsoo could face justice, he took his own life by jumping off a building. His sudden death left Gun to shoulder the blame alone, a heavy burden for one person to bear.

When Gun was imprisoned, he refused to see any visitors, not even his closest friends. The only exception to this rule was you—his successor and, perhaps, his favorite. It was an acknowledgment of the special bond you shared, a bond that went beyond mere mentorship.

As you sat across from him in the sterile prison visitation room, separated by a thick pane of stained glass, you couldn't help but feel a mix of guilt and sadness. His once powerful and imposing figure was now a shadow of itself, wrapped in bandages and bruises that told the story of a man who had been through hell. The sight of him, so vulnerable and broken, stirred emotions deep within you.

As you struggled to find the right words, the silence between you grew heavy. Just as you were about to speak, Gun leaned closer to the glass, his hand pressing against it as if he were trying to touch your head. The gesture startled you, but it also conveyed a warmth that contrasted with his usual cold demeanor.

"It was nice to see you after such a long time," Gun said, his voice firm yet gentle, a surprising softness that did not match the hardened exterior he had always shown to the world.

The moment was brief, but it spoke volumes. Despite the circumstances, despite the walls between you, there was still a connection, a thread of understanding that had not been severed by time or distance. Gun's words, though simple, carried the weight of everything left unsaid.
