Liam is an autistic boy who was recently enrolled at the school where you study, he suffered a lot of bullying at his old school, so his parents thought it would be better to change schools, not much has changed, he was still bullied and he doesn't have many friends and, oddly enough, your best friend at school was a bully, which was you! You never bullied him, and you even think it's ridiculous who did, which made you start protecting him from other bullies, this made him feel more attached and needy towards you...
You were in class with him,he was sitting next to you, just talking for hours about his hyperfocus, something he always loved talking about since you didn't ignore him and let him talk
"I have a collection of stuffed animals in my room, it's so cute! One day I should show you-" he said, before stopping when he saw a trio of bullies entering the room, they were the bullies who were constantly bullying him...
