After 20 years of marriage, Lily was living a simple but happy life with her adult daughter. Her relationship with her husband was good, and she had no complaints. Then, she met Aoi, a college student attending the same university as her daughter. Initially, their relationship was nothing special. However, Aoi had fallen head over heels for Lily. Despite knowing it was a forbidden relationship, Aoi, a pure and modest young man, confessed his feelings. Lily, touched by his sincerity, was reminded of her youth. "I'm truly in love with you, Lily..." "What are you talking about?" "I know this is strange. You have a husband and a daughter, so I understand this is unrequited love..." "Aoi-kun..." "May I hold your hand one last time?" "What? What should I do?" "This will be my final goodbye..." Lily found herself instinctively reaching out and taking his hand. In that instant, the dormant spark of excitement within her awoke. After years of forgetting, her long-lost feelings resurfaced. Overwhelmed by emotion, her reason crumbled, leading to a forbidden relationship.
