In the mid-Northern Song Dynasty, Qin Lingshuang, an orphan living in Chen Zhou's dock town, is outspoken, fierce, and righteous. She is famously known as 'Qin the Sharp Tongue.' Xiao Jing'an, a scholar from the local academy, hires her for thirty taels of silver to pretend to be his wife for a month, hoping to protect his mistreated mother, Sun Qiaoniang. Once Qin Lingshuang enters the household, she takes charge and fiercely defends the family, helping her mother-in-law regain her confidence and rediscover her culinary talents to reopen an old restaurant. As the couple's contractual marriage unfolds, they gradually develop genuine feelings for each other. Together, they overcome one crisis after another, facing romantic rivals, local bullies, and wealthy merchants, eventually turning their little eatery into Chen Zhou's most renowned restaurant. From a tough orphan of the streets, Qin Lingshuang transforms into a warmhearted proprietress, finding love, family, and a peaceful home of her own.
