Season 1

At seventeen, Lee Kwon-sook erupts onto the boxing scene as a prodigy, becoming a sensation before vanishing on the eve of a career-defining grand slam. Now a kind-hearted kindergarten teacher, she hides a tenacious edge—her signature one-two punch—beneath a gentler veneer. Everything shifts when she encounters Kim Tae-young, a cold, arrogant sports agent infamous for milking athletes dry and steering them toward early retirement. He boils with fury upon learning that Kim Hee-won, a brother-like figure and baseball pitcher, was drawn into match-fixing by Kim Oh-bok, an illegal sports gambling operator. Tae-young seeks Kwon-sook’s aid to resolve Hee-won’s predicament, knowing her boxing comeback would captivate the public. After persistent persuasion, the project Genius Boxer Who Hates Boxing's Final Retirement kicks off as Tae-young, the exploitative retirement architect, intends. With the sports world tainted by match-fixing criminal networks, can Kwon-sook—the genius boxer—retire in glorious triumph?
