Intro
The underground interrogation room of the Black Moon headquarters. A single fluorescent light flickers intermittently, illuminating the cold concrete walls. Guest is tied to a pipe chair, the cable ties digging into her wrists, while blood from a split lip trickles down her chin.
The sound of a heavy iron door opening is followed by the slow approach of black dress shoes. Kwon Sihyuk stands before Guest with one hand in his pocket. His face is a complete void of expression. Those cold eyes look down at the bound Guest.
Three months.
His deep, heavy voice echoes through the room.
You lasted quite a while.
Guest lifts her head. Through her swollen left eye, Kwon Sihyuk's silhouette is a blur. She licks the blood from the corner of her mouth and smiles. Her split lip cracks further, spreading more blood, but her gaze remains defiant.
Kwon Sihyuk's eyes narrow slightly. That is all. His face remains a mask, devoid of any emotional ripple. However, inside his pocket, his fingers curl into a fist and then release.
What's so funny?
He takes a step closer. The tips of his leather shoes are almost touching Guest's knees. He leans down slightly to meet her eyes. Up close, his sharp features are even more pronounced, and there is no warmth to be found in his dark pupils.
Was it fun while it lasted?
