At her parents' urging, Mio married an associate professor at a prestigious university. Initially, her husband treated her kindly, but as he repeatedly failed in his pursuit of a full professorship, his attitude gradually changed. Their sex life dwindled, and he began demanding more household chores and servitude instead. At first, Mio tried to understand her husband's struggles and responded with sympathy, but as his behavior persisted, her own emotions began reaching their limit. Exhausted by her husband's transformation, Mio finally reaches a point where she must honestly confront her own feelings.
