In an era where love and marriage are weighed by cold, hard numbers—where no one wants to end up on the losing side—two jaded souls find an unexpected spark. Hyun Da-young, 35, is the picture of success: a career woman who’s checked every box in life… except marriage. Time is ticking, and society’s pressure is suffocating. Choi Woo-jin, also 35, is a commitment-phobe who’s convinced age gaps doom relationships—thanks to his older sister’s failed marriage. He’s given up on love entirely. But when these two collide, something unpredictable happens: real feelings. Now, they face a dilemma—can they ignore the societal math (and their 10-year age gap) to embrace a love that defies logic?”
