Modern-day slacker Su Qinghuan unexpectedly transmigrates into the Great Yao dynasty as the spoiled Princess Anning, who has been jilted and tried to kill herself by throwing herself against a pillar. When the emperor scolds her, “I don't mind you being spoiled. I mind you not striving to improve,” she digs in her heels, refuses to hustle, and fires back at everyone with her delightfully unhinged attitude. To her surprise, she catches the eye of Xiao Jingyuan, the aloof and immensely powerful Prince Jingyuan.
She doesn't study, learn etiquette, or scheme for power. She focuses on food, fun, making money, and lying flat. Yet her clever modern business ideas make a hit, and she uses her sharp tongue to take on her critics, face-slapping the fake innocent and her former fiancé. When the Empress Dowager arranges her marriage to Xiao Jingyuan, she fears she'll have to strive after the wedding and tries to run away. Xiao Jingyuan gently promises her, “Marry me. You can be as spoiled as you like. You don't have to strive at all.”
After the wedding, she lets herself go completely, shamelessly slacking off in the prince's estate while her husband dotes on her and the entire royal family adores her. When a food crisis strikes, her unintentional actions resolve it, completely transforming her reputation. In the end, she becomes the envy of the entire capital: she doesn't work hard or strive for success, yet someone shields her from every storm so she can live a happy, peaceful life. At last, she gets to enjoy the delightfully unhinged dream of slacking off and winning at life.
