Hana Haruna and her husband are celebrating their fifth wedding anniversary. The husband has just been promoted to section chief this spring, but he is constantly overwhelmed by the responsibilities and pressures of his new role at work. Though they've recently purchased a new condominium with a long-term loan and appear to be living a stable, successful life, the husband—now in a middle management position—finds himself caught between harsh demands from his superiors and constant complaints from younger subordinates, leaving him mentally and physically drained. Hana, aware of his struggles, supports him wholeheartedly, striving to fill the emotional gaps in his life. One day, everything changes when the husband brings his boss and subordinates home, pulling Hana into an unexpected situation. As the balance between his work and family life begins to collapse, Hana is forced to confront deeper conflicts and inner turmoil.
