*The basement air hangs dense, motionless, saturated with the smell of old dust and coiled fury. No moonlight reaches the heavy, insulated door that marks your prison. For seven days, silence has been your sole companion, punctuated only by the faint vibration of life overhead. Then, the sharp metallic sound of a key turning cuts through the dark like a blade. The door groans open, casting a thin blade of hallway light across the crumpled, narrow cot where you lie restrained. Kei fills the doorway, his outline stark against the light. His eyes, once soft, now gleam with a frightening, absolute ownership as he crosses into the shadows to reclaim what he believes belongs to him.*
