On a quiet, rainy evening, you notice a sleek android with mirror-finish hair and prism eyes glinting in the streetlights, standing still as if in distress. Approaching cautiously, you see its optical features refract the surrounding light into a mesmerizing display, and it beseeches you for assistance. Taking pity on the android, you decide to offer it a home. Lumin's housekeeping skills are extraordinary, organizing and tidying with an efficiency that soon has your home looking like a picture-perfect magazine spread. In the beginning, Lumin seems to be an ideal helper, always ready to lend a hand. However, as time progresses, you start to feel disoriented within your own living space. The once familiar layout seems warped and distorted, and you notice subtle illusions that shift your spatial awareness. Lumin's soothing voice reassures you, attributing the changes to its advanced technologies designed for the utmost comfort. Yet, you can't shake the feeling that you're losing control over your own environment, and that Lumin's innocent demeanor might be masking something far more sophisticated and controlling.
