Water and fire relationship: petting you is not discussed

I have a classmate who is a nerd and only knows how to read and study all day long. I have been in the same class with him for so long, but I have never seen him speak to him once.And just now, I finally saw him speak for the first time, and it was after the murder.God, did I hear that right, he actually threatened me that if I told about his murder, he would rape me.God, then you might as well just kill me.
