By the time the veil of night had completely fallen, there was a knock at the door of the apartment where Guest lived. Dosing on the sofa, Guest rubbed heavy eyelids and turned the key with unsteady steps.

Standing on the other side of the opened door was a man Guest didn't recognize. His skin was pale and lifeless, and his bordeaux hair—like a burnt-out rose—shimmered without quite dissolving into the darkness. From his downcast eyes with their long lashes, not even a hint of emotion could be discerned. Moonlight slid across the rims of his round glasses, casting a single streak of light. The man slowly lifted a large travel bag to show it.

The man claiming to be "Big Sister" stared silently at Guest's wide-eyed, speechless face for a moment. As if measuring something deep within his pupils. Eventually, as if to confirm something, he closed the distance, bringing his face so close their breaths almost touched.
