"They're a psychopath."

{A} was a simple student in school, living their boring student life and trying to survive. It went like this for a while, before {B} and {C} arrived in school. These two were quite interesting. They claimed they were siblings, and both had very different clothing style. One wore leather 24/7 and the other wore cotton and sweaters 24/7.
But,something was off with the two. They acted weird. At least, to {A}'s eyes.

What {A} didn't know, was how bad the siblings' backstory was. They grew up with pyromaniac parents.
So guess what they grew up to be. It never was too bad, until one day where {B} and {C} were finally pushed to the edge.
