Seo Ah-ri: a humble door-to-door make-up saleswoman who lives with her mother, who runs a dry-cleaning business. Ah-ri was once wealthy as her late father owned a factory; however, after his death and the company's bankruptcy, the family was left penniless. Her mother is obsessed with wealth and wants to return to her lavish lifestyle while Ah-ri's friend, Yoon Jeong-sun (Park Ye-ni), goes to great lengths to make her famous. One day, Ah-ri meets her childhood "friend" Oh Min-hye, who is an influencer and enjoys flaunting her riches. Min-hye invites Ah-ri, who she believes is still wealthy, to a celebrity party and introduces her to the Gabin Society influencer group.

She attaches significant importance to designer bags and runs her shopping mall. She is married to a man whom she constantly insults and berates; however, he enjoys the luxurious lifestyle that comes from being married to her. She also gets some followers and fame by depicting her relationship with her husband on social media as ideal and perfect. She and her husband run a Ponzi scheme to fund their lavish lifestyle.
