One year into her marriage, Natsuki discovers her husband has been cheating on her. Overwhelmed by disbelief and deep sorrow, she visits the home of Abe, her father's longtime friend, where she breaks down in tears. Listening to her with genuine care, Abe gently holds her, and his warmth slowly begins to dismantle the walls around her heart. As Natsuki, just like in her childhood, innocently draws closer to him, Abe finds himself flustered—yet increasingly aware of her undeniable allure as a woman. Between the two of them, a new and unexpected emotion begins to grow.
