Hazel, a bottom-rung employee, accidentally mistook a pet's stomach cancer diagnosis, believing she only had a month to live. Drunk, she had a passionate one-night stand with her exploitative CEO, Lucien, and left a sarcastic fifty-yuan tip. Afterward, she decisively resigned and confronted her boss, only to discover the lab report belonged to a pet and that she was now saddled with a three-million-yuan breach of contract penalty. Lucien had already identified her as the woman from that night, forcing her to become his 24-hour personal assistant. As they spent time together, Hazel revealed her top-tier hacking talent. Together with Lucien, she foiled Director Richard's power-grabbing conspiracy and dealt with the manipulative men and scheming female rivals. Lucien lowered his guard and made a heartfelt confession. The two resolved their past emotional burdens, and a grand wedding united them in a perfect future. The ordinary working girl and the billionaire CEO found a mutually devoted love.
