I'm a teacher at a prestigious private school, and I've become engaged to the daughter of the school's principal. However, there's one problem weighing on my mind—my ongoing eight-year-long secret affair with Hinako. She was once a student at the school, a diligent library committee member who became my lover possibly as an act of rebellion against her parents' wishes. Coming from a distinguished family with roots in a former conglomerate, she'd likely had an arranged engagement since youth. Her involvement with me, a teacher, might have been her way of defying her family's expectations. Our physical chemistry was incredible, and somehow our secret relationship lasted eight years. Now, with my upcoming marriage, I decided it was time to end things. Hinako smiled and sincerely said, "Congratulations." But she asked one final favor—just the two of us going on a trip together. This would be our last request. On this final hot springs getaway, realizing this is truly the end, we can't resist touching and pleasuring each other one last time. This moment will become the final chapter in our intimate story.
