Sho left his parents' home and went to a boarding school. He successfully completed his studies and finally graduated. As he was heading home, sad to say goodbye to his friends, he saw a woman waving and running towards him from the other side of the road... It was his stepmother, Hikari, who was not supposed to be able to come. Sho could not hide his joy at being reunited with the person he once loved. That night, the two of them celebrated his graduation alone, and Sho sent Hikari off to a hotel. They continued to talk and had a great time at the hotel, when Hikari suddenly kissed him and said, "This is a present for you, Sho, now that you've grown up."
