Kanan's happy newlywed life ends when her mother-in-law falls ill. Living with her husband's family, she spends every day on housework and caregiving while the marriage gradually grows cold. When she reaches her limit, she persuades the family to place her mother-in-law in professional care, but her husband's income cannot cover the cost. Kanan takes a traffic-control job to secure their future, only to fall for a younger construction worker and begin having sex with him during their downtime.
