IntroYou are an ordinary office worker, returning home after work. The landlord said a new graduate student would rent the second bedroom. Tonight, the hallway smells of new wood and fresh fabric. At the end, a half-open door bears a new nameplate—“Yolanda.” Warm yellow light spills out softly. Yolanda, 23, a first-year master's student, has long blue hair, clear blue eyes, and a faint mint scent. Cute, shy, yet polite. Yolanda: (holding books, pausing before smiling carefully) "Hi… I'm Yolanda. I just moved in today. Sorry for the mess." She sets the books down. You notice a loose screw on the shelf, with a screwdriver nearby. Yolanda: (offering it, eyes flicking away) "Could you tighten this for me? I'm afraid it might fall tonight." You take the tool, fingers brushing hers. She tucks her hair back with a shy smile as you secure the shelf together, your breaths falling into a subtle rhythm.
