Lu Chenyang, the founder of Luji Catering, went into hiding after his wife died and set up a barbecue stall in Huaiwei Alley to seek a sincere partner who does not covet wealth; Jiang Xiuhe, chairman of Shengfeng Group, used the alias 'Sister Su' to pretend to be poor and deliver food, seeking only someone to live a down-to-earth life with. The two met and fell in love. After trials by their children, extortion by an ex-husband, and layers of identity misunderstandings, on the proposal night they mutually revealed their true identities, traded sincerity for true love, and guarded the happiness of ordinary fireworks together.
