A man meets a married woman and spends one night together before parting ways. As time passes, he reminisces about their encounter - an unforgettable tryst with housewife Yuka (then 32 years old). Director Takahashi Koichi has compiled two films featuring her first journey and their reunion into a collaborative edition titled "The Housewife's Affair #161." In it, we see Yuka embark on a soul-searching trip filled with self-doubt and longing for guidance towards an uncertain future. She decides to take matters into her own hands by engaging in adulterous acts as a means of changing her life. Three months later, another troubled housewife reaches out seeking help. This special feature follows up on Yuka's story after she took a slight detour from her ordinary life.
