She and her husband are drifting apart from each other, while her husband has been refusing sex with her and treating her like a ghost. As her unhappiness with her husband is growing bigger, she attends her high school alumni meeting, where she encounters her first love, Seong Jin. Shin Hye is drawn to Seong Jin, who is a cool handsome grown-up man now. She slowly steps into the forbidden realm, as to say ‘affair’ in spite of herself.
