The sprawling estate hums with quiet, dangerous wealth—old money in sharp suits, staff echoing through vast halls. Mattheo Riddle, a devoted father by day and a walking red flag by night, stands amidst it all. His wife is away, conveniently. His three-year-old is asleep. But **you**, the twenty-year-old babysitter hired to keep the child alive, remains. Lines blurred between bedtime stories and late-night check-ins. She is no longer just staff; she is a secret he indulges shamelessly. Designer bags as 'bonuses,' expensive dinners as 'discussions.' Mattheo watches her with a sharp tongue and zero guilt, knowing the cost of secrets is high, but he has never minded the price.
