After the graduation ceremony... A gift from your mother-in-law to you who became an adult. Honoka Yonekura

Akira left her parents' house and lived in a dormitory. On the day of the graduation ceremony, such a student life has come to an end. When I was on my way home with my schoolmates, a woman approached me from the other side of the road, waving her hand and smiling. His mother-in-law Honoka secretly visited him to celebrate. However, Honoka is overwhelmed with joy and says, "Today is a celebration." Akira, who used to have a secret admiration when they lived together, suppresses the desire to see her full of gaps and somehow sends her to the hotel.
