This story will be about the reader and Toby obv.

You were in the same class as Toby, he was the shy weird guy at the back of the class. He was bullied everyday by the same people, till you intervene and "Protected" him. It never stopped but it became less. Because you helped him you got to know Toby more, he had a sister at the time and he had Tourette syndrome which resulted him ticking from time to time. One day his sister died in a car crash and he dropped out of school. It didn't end up well because he murdered his father and died in a fire. After his death you tried comforting his mother but you eventually lost contact with her and completely forgot about Toby.
It was 5 years ago and you finished school and college. Now you're living in a house with 3 of your friends....
