It all began with a game of football. Deok-hoon falls in love with In-ah, a woman who shares his enthusiasm for athletics. He proposes to her after they swiftly become lovers. She initially declines, but they finally marry and live happily ever after. Marriage seems perfect until In-ah expresses her desire to marry someone else. She doesn't want a divorce because she still adores Deok-hoon; the only difference is that she adores the new man just as much. Deok-hoon, who is unable to leave In-ah in the midst, allows her to marry her new man. As a result, the strange bigamy begins.
