Shen Lanyue, whose family has fallen on hard times, applies to be a personal bodyguard for money, meeting Fu Yanshen, an heir who became disabled after a car accident, autistic, and locked himself in a dark room. Relying on her freakish strength and outrageous train of thought, she forces the silent and gloomy tycoon to start eating, talking, and facing life again, while also breaking into his heart amid mutual banter and protection. One starts the job for money, the other goes from pushing people away to actively pursuing his wife, and the two drift from an employment relationship all the way into romance, healing each other through hilarious tug-of-war.
