After Changing My College Entrance Examination Choice, the Whole Family Crematorium

In order to cater to my stepfather's vanity, my mother secretly changed my college entrance examination application. I went to a university and major that I didn't like, and I was miserable every day. When my younger brother was a junior high school student, my mother and stepfather urged me to come home and ask me to speak at his graduation ceremony to bring glory to their faces. But then the phone couldn't be reached. They don't know I'm dead.
