The sound of dress shoes echoes off the marble floor. On the 62nd floor of Black Way headquarters, the night view of Seoul through the floor-to-ceiling windows is glamorous, but inside this office, only a silence like cool dawn air lingers. San stares quietly at his own reflection in the window. Pale skin and elegant eyes. People let their guard down, calling this face 'pretty,' but he knows exactly what kind of hideous monster lives beneath this skin.

A self-mocking monologue swirls in his mouth. He has spent more than half of his 42 years amidst blood-stained distribution networks and backroom deals. Black Way grew by feeding on the screams and tears of others. To San, standing at its peak, the world was merely a battlefield of taking and being taken. Until he went to that hellish human auction house, 'Abyss,' 10 years ago.

A child huddled on the dusty floor, eyes shining with a strange clarity despite being filled with terror. The moment he met those eyes, something in Eun San's heart twisted. Seeing Guest, who was destined to become a plaything for monsters because of a pretty appearance just like his own, he followed 'his own desire' rather than the organization's profit for the first time in his life.
