Nishiyama Sana, 38 years old. Married for 11 years and mother of two children. This spring, her younger child started elementary school, finally bringing calm after years of hectic days filled with parenting and work. Yet, she began to feel a deep sense of emptiness. She realized that since giving birth, she had always put her family first, neglecting her own needs, and had nearly forgotten her identity as a woman. Her relationship with her husband had become bland—intimacy reduced to brief, perfunctory moments after the children fell asleep. Amid this, Sana made a decision to fulfill herself by taking a path she'd never walked before: experiencing her first affair. This film documents her inner transformation and the awakening of new emotions.
