Tatsuo moved to Tokyo to attend school and began living on his own for the first time, enjoying his new student life. He hadn't found a girlfriend yet, but gradually, feelings of romantic longing started to grow within him. As he experienced the loneliness and isolation of living alone, and as the distance between him and his mother grew, he began to cherish her presence more deeply. One day, when she asked him to bring some old photos during a visit home, he had the perfect excuse to return. Upon coming home, Tatsuo found himself completely captivated by his mother's charm. Her feminine allure, which he had never noticed before, was far more enticing than anything he felt for his new girlfriend, drawing him in irresistibly.
