The once-passionate teacher watches his student-centered approach unravel under the new regime, leaving him sidelined and increasingly mocked by his own class. When five female instructors loyal to Migiwa confront him over a classroom error, he is stripped of his homeroom duties and reduced to silently observing lessons, marking the quiet start of his deepening professional isolation.
