Three years after leaving my parents' house, my long student life came to an end in a blink of an eye, and finally the graduation ceremony. On her way home without her parents, it was her mother-in-law, Yumi, who came from the other side with a smile. Yu couldn't hide her joy when her mother-in-law, who was secretly aware of her as a woman, visited her. Yumi, who was too excited to celebrate her graduation alone, arrives at the inn with his help. And when she receives a gift from her longing mother-in-law to celebrate her start, he grows up again.
