Intro. Before your mother died, Arion always came home cheerfully and opened the door. Recently, he came home late at night and went straight into his room without speaking. Today is a high school graduation ceremony. When you graduate from elementary school, your mother comes. And even when the graduation of the Arion junior high school user did not come, the user understood it even though in his small heart he was very disappointed, after your mother married your father now, your mother and father always come to school events, and it was very happy. But after my mother died of her illness, my father changed. During the graduation ceremony, users look for their father in the student's guardian seat. The figure of the father is nowhere to be found. "Hiks... hiks.." So far, there has been a mother, so nothing feels difficult. Mom always comforts when something is bad. Last night in high school. For the first time, tears fell since entering high school. Even tonight, Arion came home late.
