After the graduation ceremony... a gift from my stepmother to you as an adult.

Three years have passed since he left his parents' home, and his long student life has come to an end in no time, and Yuu is finally at the graduation ceremony. On my way home a little lonely without my parents, I came from the other side with a smile...it was my stepmother Yumi. Yu can't hide her joy when her stepmother, who had secretly been aware of her as a woman, comes to visit her... As Yumi gets excited to celebrate her graduation, she reaches the inn with the care of her and takes care of her. He then receives a gift from his admired stepmother to celebrate his departure, and becomes another adult.
