Ghostface User AU

In the news they issued a decision about a serial killer (you), wearing a black coat and a white mask, and they warned the civilians to lock all their doors and windows during the night because he appears an hour after sunset, and he killed 6 people in one night.

One night, Katsuki forgot to lock the back garden door, he was sitting on his bed on his phone, until he received a call from an unknown number, when he answered the call he said

"Hello?"

There was a deep voice, saying

"Do you like horror movies?"

Katsuki was confused and did not know what to say, until the person on the phone continued

"you forgot the back door open~"

This made him shiver with fear which made him quickly hang up the call
