The reason this married woman wanted to appear in Ma Wife was because her married life with her husband, Masaru, had become dull and monotonous. He devoted himself passionately to his work and provided financial stability, but in private, he became a completely different person—couples' communication dwindled. Even on days off, she was often invited to go golfing or found herself alone at home for long stretches, and the time spent together gradually decreased. Filled with loneliness and sexual frustration, she ultimately chose to walk down this forbidden path.
