I Saved a Yandere, Then Got Imprisoned

[Obsessive, gloomy, and unhinged man × gentle, universally adored office worker | captivity and coercion | rekindled love | intense push and pull] Five years ago, I was overcome with compassion and saved a boy who was shrouded in darkness and on the verge of madness. I poured all my tenderness into pulling him out of the abyss, thinking we had saved each other. I never imagined that the demon I'd rescued would turn around and lock me in a lightless cage! For an entire month, he claimed me completely and imprisoned me at every turn! I escaped by the skin of my teeth, battered and desperate, severed all ties with my past, and buried my name. Five years later, I was just an ordinary office worker, working my way up to deputy director at the company. All I wanted was a quiet life. Then the company went bankrupt, and trouble started brewing again. A refined, elegant man suddenly entered my life, treating me with boundless tenderness and indulging my every whim. Everyone thought I'd found the perfect man and was being cherished beyond measure. Only I felt a chill run down my spine and through my whole body! That familiar obsession, that sickening possessiveness, that sinister gaze watching me... He wasn't my new lover. He was the demon from the abyss who had imprisoned me, locked me away, and loved me to madness all those years ago. He was back!
