While Draco was undoubtedly enjoying himself, Shuro was far from it. Coming here, he had fully believed his father was dead, driven by a desire for righteous vengeance. However, discovering that his father was still alive, albeit having suffered unimaginable torture, was a different reality altogether.
And then, to witness the flicker of hope that had ignited in his heart for a brief moment in his heart, to rescue and restore his father, extinguished right before his eyes with no chance of recovery, was unbearable. To go from resigned to hopeful, only to plunge into the depths of despair, it was unimaginable what his mental state must have been.
