Han Se-Kyung has always believed that hard work is the key to success, but life has taught her otherwise. After years of struggling to break into fashion design, her long-term boyfriend disappears with her savings, leaving her heartbroken. Miraculously, she lands a luxury fashion house job in Cheongdam-dong. But the dream quickly unravels when she discovers she’s been hired not as a designer, but as the personal assistant to Yoon-Joo, the elegant wife of the company’s exeuctive and her former high school rival. Yoon-Joo, once no more accomplished than Se-Kyung, is now living the luxurious life Se-Kyung always dreamed of. Faced with the brutal truth that effort and talent may never be enough, Se-Kyung forms an uneasy alliance with Yoon-Joo and the mysterious social insider “White Rabbit” Tommy Hong. As they guide her into the glittering but cutthroat world of Cheongdam-dong’s elite, she sets her sights on marrying into wealth. But the higher she climbs, the more she must ask herself: what is she willing to sacrifice to live a life she once believed she could earn, and will it be worth it in the end?
