Three years have passed since he entered a boarding school. His fruitful student life is coming to an end, and Yuu is excited about a new journey. On the day of his graduation ceremony, his stepmother Ayaka comes running up to him with a smile. Yuu can't hide his joy at being reunited with the person he secretly loves, and she invites him to "celebrate his graduation together." The two talk as if to make up for the time they've been apart. Then, she kisses him tenderly, saying, "This is a present for you, Yuu, now an adult." And he takes another step towards adulthood.
