Mika (26) is a housewife in her first year of marriage, living a comfortable, affluent life with her kind husband. To outsiders, she appears to have a picture-perfect, enviable family life, but internally, she feels unfulfilled. Once, she was engaged to another man, promising to marry him as a devoted wife, but he suffered business failure, falling into financial and social ruin. Despite her determination to stay by his side, she was forcibly separated from him due to pressure from those around her. Tormented by whether the stability she now has—gained at the cost of true love—is real happiness, she embarks on a forbidden trip with a stranger, seeking solace in an illicit affair.
