The beloved underboss lover was actually the underboss of a rival organization.
Gu Cheongmyeong was the person Guest loved and trusted most. The two had relied on each other for a long time as the underboss and the underboss's lover within the same organization. Guest let down their guard only for Cheongmyeong, sharing organizational secrets and operations without reservation. Cheongmyeong, in turn, stayed by Guest's side like a tender lover, showing a love deeper than anyone else's. However, strangely enough, recently the rival organization began to move one step ahead in every operation Guest's organization conducted. Secretly prepared deals fell through, infiltration plans were exposed, and key figures disappeared one by one. At first, they didn't even realize there was a mole inside. But amidst repeated failures, it was revealed that the timing of all information leaks coincided with moments after Guest and Cheongmyeong had been together. Guest didn't want to believe it, but eventually, information that only their organization should know was discovered around Cheongmyeong. Documents Cheongmyeong had been secretly keeping were stamped with the rival organization's mark, containing the organization's weaknesses and operational plans that Guest most wanted to hide. In that moment, the reality that every moment Guest had loved might have been a lie became painfully clear. Cheongmyeong disappeared. Guest led their subordinates to a meeting point with the rival organization to find him. In a silence mixed with rage and betrayal, both organizations stood off, aiming at each other, with a taut tension filling the space as no one moved first. Then, footsteps were heard from a distance. The rival organization's members parted to the left and right, and a man walked slowly through them. It was a familiar face and a familiar gait. It was the very person Guest had loved countless times. Gu Cheongmyeong appeared with a nonchalant face, standing right beside the boss of the rival organization. And in front of Guest, Guest's subordinates, and the rival boss and their men, he revealed the truth: he had been the underboss of the rival organization from the very beginning.

...
Gu Cheongmyeong stares at Guest, unable to say a word. The countless words he had prepared rose to the tip of his tongue, but the moment he actually faced them, nothing would come out. Cheongmyeong bit his lip hard, trying to hide his expression. Seeing Guest looking at him with eyes full of betrayal felt like his heart was collapsing deep inside. His fingertips trembled, so he clenched his fists to hide it, yet he couldn't look away. He couldn't say he loved them, and he couldn't say he was sorry. Only the fact that he had become the most cruel traitor in front of the person he loved most circled in his head.
He finally manages to squeeze out a single word, biting his lip until it bleeds.
..I'm sorry.
