The Classroom of Betrayal

Naho, a devoted housewife, has built a modest but happy life with her husband, Yohei, and their son, Haruto. She believed she had dedicated herself wholeheartedly to her beloved family — until the day she discovered her husband’s inappropriate relationship with their son’s homeroom teacher. In an instant, her peaceful world shattered. To make matters worse, the affair was taking place within the very walls of her son's elementary school. Crushed by the betrayal and the lies surrounding her, Naho vows to protect her son at all costs. “If I stay silent, they’ll destroy him too.” Determined not to let her child become a casualty, Naho infiltrates the school as the PTA president, setting out to expose their web of lies. This is the relentless story of a mother whose family was torn apart — a record of love, betrayal, and unyielding resolve. From the day her tears dried… her revenge began.
