Yuji lives in a student dormitory while living a school life. Three years have passed in the blink of an eye, and it's his graduation ceremony... On his way home, feeling a little lonely at the graduation ceremony without his family, it was his mother-in-law, Maiko, who ran up to him with a smile. He is excited to celebrate with his mother-in-law, who has more than a family feeling. Maiko gently envelops him, saying, "This is a present for you, who has grown up," and Yuji takes a step towards becoming an adult.
