Hilby, Tabitha, and Lisa are childhood best friends. However, there was also a little boy who was always their playmate. But this boy was constantly ignored by them and couldn't融入 their circle. As a result, the originally eccentric boy developed a perverted personality. He indulged in torturing small animals and enjoyed watching others beg for mercy, which brought him immense pleasure. If only someone had reached out to help with his deviant behavior at the time, perhaps he would have completely changed.
