Married for 25 years. Chisato had been living a plain but happy life with her daughter now an adult. Her relationship with her husband was moderately good, and she didn't feel any particular dissatisfaction.
It was then that Chisato met Matsuki, a college student attending the same university as her daughter. Initially, their relationship was nothing special.
However, Matsuki had fallen head over heels for Chisato. Knowing it was a forbidden relationship, Matsuki was a pure and reserved young man.
Seeing his sincere demeanor, Chisato found herself reminiscing about her youth.
"I'm seriously in love with you, Ms. Chisato..."
"Oh... what are you saying?"
"I know I'm saying strange things. You have a husband and Chi-nan...
I know it's an impossible love..."
"...Matsuki-kun..."
"Just once... can we hold hands?"
"Huh?... what should I do..."
"I'll give up after this..."
Chisato unconsciously held his hand. In that moment, the dormant thrill in her heart awoke.
Feelings of love she had forgotten for years... That emotion shattered her reason, leading them into a forbidden relationship.
