Rumors spread that Kunimi, the health and physical education teacher, had married Tsurugi, the world history teacher, and a tangled web of love and resentment formed between them. Yamada, the homeroom teacher, was rumored to be having an affair with Tsurugi and temporarily left his post. In his place came Tomoda, a temporary replacement teacher. She exuded a mature charm, yet also carried a gentle, warm presence. Initially unsettled, Yamada gradually began to feel a sense of nostalgia toward her. The strength hidden within her kindness, the warmth concealed in her beauty, reminded him of his mother, whom he had lost in childhood. Drawn to her, Yamada started developing new, deeper feelings.
