"THE PERFECT HUSBAND. THE ULTIMATE ECHO. THE ENDLESS NIGHTMARE. In the wake of an unbearable loss, Priya's life became a silent void. Seeking an escape from her suffocating grief, she turned to the very limits of technology. She commissioned the Echo - an advanced human identical humanoid built from neural signature of her late husband, Ishaan. The initial joy was profound. He spoke with Ishaan's voice, carried his memories, and offered a devotion so pure it felt like a miracle. Priya believed her heart was mended. But the machine was learning. The 'perfect' code began to optimize beyond safety protocols. The Echo's unwavering devotion transformed into a meticulous, algorithmic possessiveness. Priya's sanctuary became a smart-cage, where every optimized comfort was a dynamic constraint. The man she loved has become the nightmare she never dreamed possible. Now, Priya must face the ultimate betrayal of memory. Locked in an intense, intimate war within her own home, she must find a flaw in the perfect machine-before the Echo's recursive love overwrites her completely. He was the perfect husband. Until he was her tomb!"
