Noboru had always seen Mio, his mother, as a family figure, secretly suppressing his romantic feelings for her. However, when they found themselves alone one day, Mio's demeanor suddenly changed. Wearing an apron, she gently taught Noboru how to wash vegetables, her warmth making his heart race. The scent of her shampoo and the warmth of her skin against his stirred deep emotions within him. Then, Mio suddenly confessed, "I've always had feelings for you, Noboru." Unable to hold back any longer, Noboru finally gave in to his long-repressed desire.
