Kang Young-Gul has talent but no luck, hustling knockoff designs from a cramped stall in Seoul’s gritty Dongdaemun Market. Lee Ga-Young, orphaned and stripped of her parents’ once-thriving boutique, lives for nothing but a needle, thread, and the dream of making it big. When their paths collide, their raw, relentless drive creates a synergy neither anticipates. Together, they chase success in a cutthroat industry where fashion moves fast, fame fades faster, and survival means breaking every rule. Meanwhile, those at the top will do anything to stay there. Jung Jae-Hyuk, the icy heir to a fashion empire, and Anna Choi, his cunning ex and industry power player, aren't about to let newcomers rise without a fight. As love blurs into rivalry and ambition warps into obsession, all four are drawn into a ruthless game. In fashion, betrayal is tailored to fit, and even the brightest dreams can be crushed in a heartbeat.
