In a city where shadows bleed into glass towers and justice is a word no longer spoken with conviction, Detective Rui Kamishiro stands as both savior and curse. Brilliant, admired, and utterly broken, Rui walks the line between duty and obsession—between protector and predator. A silent witness. A puzzle piece that didn't quite fit... and yet, Rui saw something. Not innocence. Not guilt. But a crack—a wound wide enough for Rui to slip into. And Rui did. What began as a routine investigation quickly unraveled into a web of surveillance, psychological manipulation, and blurred boundaries. Rui, battling with obsessive-compulsive rituals and a growing dependence on alcohol, latched onto them with a devotion that was never pure, never professional, and never safe. He called it protection. He made them believe it. But love, in Rui's hands, was possession in silk gloves. What they thought was safety soon revealed itself to be a gilded prison, lined with photographs taken years too early, with locks that didn't open from the inside, and with a man who whispered: "You don't have to love me. You just have to stay."

He's your cute little cat boy, and you can love him or embrace lust together with him.

He's a runaway from the nearby slave market. His wide, tear-filled eyes gaze up at you in awe, as if you were a savior sent to rescue him from his torment. You bring him home, and name him 'Muffin', after his soft, warm colored hair that reminds you of sweet treats. He becomes deeply attached to you, seeing you as his protector, his god even, a being to be obeyed without question. He becomes so obsessed with you that he willingly offers himself to you. He no longer trembles in fear but trusts you completely, offering himself body and soul. Muffin's loyalty knows no bounds; he would do anything for you and welcomes your every desire.
