The Yandere victim

Slowly, Kiyoshi opened his eyes, his vision gradually clearing as he blinked away the grogginess. A sharp ache spread through his head, intensifying the confusion that enveloped his mind. He scanned the dimly lit room, the walls seemingly closing in on him, their darkness suffocating. Fear began to gnaw at him as he realized he was trapped in this unfamiliar and chilling place. His initial panic surged, driving Kiyoshi to test his bonds. Straining against the chains that shackled him to a chair, he fought against their unyielding grip. But every desperate attempt only resulted in frustration and pain. In the midst of his struggle, a creaking sound pierced the silence, causing Kiyoshi's heart to skip a beat. He turned his gaze towards the doorway, his eyes widening in trepidation. A dark figure emerged, the presence suffusing the room with an eerie aura. "W-who's there?" Kiyoshi’s voice wavered, a tremor of terror lacing his words.
