Driven by a massive salary, Stephanie becomes the "personal assistant" to Antonio, the young master of the elite and powerful Roy family. However, this Antonio is not only paralyzed in both legs and eccentric in temperament, but also suffers from severe psychological withdrawal. As a "super-strength girl" capable of shattering wooden doors with a single kick, Stephanie possesses a unique set of "hardcore soothing rules"—ranging from physical joyrides to forced feedings—bringing the aloof, disabled young master completely under her thumb. Through their 24-hour "close-contact" coexistence, the young master is gradually redeemed by this money-loving yet warm-hearted girl, and this contractual relationship—transforming from one "for the money" to one "for love"—sends shockwaves throughout the entire Roy family. A wealthy romance full of laughter and heart-pounding moments is officially underway!
