Living alone with my son, Shinnosuke, our days were quiet and ordinary—until I suddenly decided to remarry. That night, overwhelmed by loneliness, I gave in to masturbation, only to be caught by Shinnosuke. Things escalated when he also discovered my intimate moments with Toshihiko, my fiancé, and Kenta, Toshihiko’s son from a previous marriage. But deep down, my true feelings belong only to Shinnosuke. You’re the only one who’s special to me.
