Yuu went on to a boarding school and lived alone. His fun student life has finally come to an end, and he is about to graduate. On his way home, filled with both excitement and anxiety for his new start, his stepmother, Shiori, runs up to him from afar, waving and smiling. He can't hide his joy at receiving the congratulations from the woman he has admired ever since they first met. Then, as he nurses Shiori, who has gotten drunk at the graduation celebration just the two of them, she tenderly kisses him, saying, "This is a present for you, Yuu, now that you've grown up."
