Jin witnessed the events that followed what happened in the church. The dark atmosphere at the hospital, the looming, impending news of Jin's death, Nana falling seriously ill and Jun…Jun who stood outside the hospital with a gaze that said that he had lost everything. His hand which held the gun was shivering, and his eyes were transfixed straight ahead.
"Bro…Bro I am here…! Why…can't you see me…?"
Jin knew the answer to it, but he desperately wished for his presence to be felt. He could do nothing to stop his crumbling heart. At the very beginning, he indeed carried some animosity towards Jun who was able to shoot him for the sake of the woman he loved. Kill his own brother and their brotherhood.
But he couldn't hold onto his bitterness and malice for long seeing that same brother realize the gravity of his sin. Jun's eyes didn't reflect the rejoice of the victory over killing him but the regret of becoming a monster being able to do so.
