I feel sorry for you

ok so- uh summary: 5 years ago, a 13 year old boy stabbed his sister 12 times and burned her to ashes later on. he went to prison of course, but no one knows why he did what he did. "Both" his parents were devastated. time skip to the present; he's currently 17 years old and still living in prison. A girl named Amy was walking to school with her bestfriend Ally. some stuffs happened that made Amy question some stuffs which ended up in her finding out that Amy is actually the lil sister of the guy who stabbed his sister when he was 13 (his name is Kevin) Apparently he didn't kill her, he saved her. They had a psychotic mom that was secretly planning on killing Ally on her 11th birthday. Only Kevin knew about it from "accidently" spying on his mom. So he told it to his sister and they both decided to fake her death, even tho he would go to prison for it. tht's all i got from my dream but im already plotting on a whole thing for what's next to happen
