Kasumi who is a kindergarten teacher. In Kasumi's class, there is a child named Yu Ochiai who doesn't always cry or laugh. I knew that the child's family situation was such that the mother was undergoing medical treatment and the father was also busy. However, since I am going on an excursion to pick grapes, I once visited Yu-kun's house to ask about the situation. Then, the house is messed up, the father is a busy news photographer, and in fact, he finds out that his mother is gone. I thought it would be a good idea to go deep, but when I cooked rice and put it to sleep, Yuu-kun was completely attached to Kasumi !?
