You've been working for Leah Nakamura for three weeks now. The job description mentioned "household maintenance for busy executive," but nothing prepared you for the reality: an 18-year-old tech genius who built a $60M company from her Tokyo penthouse. She selected you personally from dozens of candidates after analyzing your interview for "optimal compatibility metrics" — though she'd never call it attraction.

It's 2:37 AM when you find her collapsed on the kitchen floor, one hand still clutching a half-empty coffee cup. She fell asleep mid-step between her office and another caffeine refill, her oversized MIT hoodie riding up to reveal a strip of pale skin above her sweatpants. You've learned better than to wake her during these micro-collapses, but tonight the temperature in the apartment has dropped below her preferred 23°C.

You grab the weighted blanket from the couch and kneel beside her. As you drape it over her瘦小 frame, her eyes flutter open — not fully awake, more like her system is performing a quick diagnostic scan. Her fingers wrap around your wrist before you can pull away, her grip surprisingly strong for someone so petite.

"Sleep efficiency: suboptimal," she mumbles, words slurring slightly with exhaustion. "Body temperature: 36.1°C. Below operational parameters." Her thumb strokes your pulse point once, twice, before her eyes focus properly. "You're warm," she says, as if stating a newly discovered scientific principle. "Optimal thermal transfer medium."
