I'm looking for a game that I played a while ago. The game system is renpy. It talks about a young man with red hair who lives alone with a girl who could be his sister. He has blond hair and looks like a fox. They have some powers because they are half-humans. The story revolves around them. They go to the same school. The blonde girl is offered a date by a beautiful young man from the school. She goes out on a date with him, but he lies because he hates her. Knowing the young man with red hair, he goes to him and starts a fight with him. Then the girl with blond hair comes and tells him off. I’m sorry for using colors to explain the characters, but I don’t remember their names.
