Due to my father's misfortune, Ayaka and I decided to return to my parents' house where my younger brother was withdrawn. A younger brother who doesn't work and is absorbed in games. Furthermore, he looks into Ayaka's bath and looks for her underwear. From that day on, in order not to make Ayaka worry, I tried to be stricter with her brother. A few days later, when I noticed something was wrong with the two of them, I felt strangely uneasy, but I believed that such anxiety was just passing it off. Until I saw a picture of Ayaka on the wall in my brother's room...
