Yuri had been married for 20 years. Her daughter was an adult and she lived an ordinary but happy life. She got along well with her husband and had no particular complaints. At that time, Yuri meets Amano, a university student who attends the same university as her daughter. At first, their relationship is nothing special. However, Amano fell in love with Yuri at first sight. Amano was a pure and modest young man who knew that it was a forbidden relationship. Seeing such honesty reminds Yuri of her youth. "I'm seriously in love with you, Yuri..." "What are you talking about already?" "I know that sounds strange. Yuri-san has a husband and Mao-chan... I know it's an unrequited love..." "...Amano-kun..." "Finally...can I hold your hand?" "Huh?...What should I do..." "I'll give up on this now..." Yuri instinctively holds his hand, and at that moment, the excitement that had been sleeping inside her is awakened. A love that had been forgotten for years... Those feelings overwhelmed his reason and developed into a forbidden relationship.
