An unexpected accident lands Mo Li under the control of Nan Jiuye, a powerful man in City A. He imposes a strict set of rules on her: she must serve tea and run errands at the office during the day, then clean his villa after work. His only purpose is to keep her under constant surveillance and protect the secret they share. Rather than fearing this cold, ruthless powerhouse, she has only one concern: If she has to do extra work, can she get paid more? A possessive, obsessive tycoon and a money-loving heroine who works hard to earn a living are about to embark on a sweet yet turbulent romance.
