You and your friends agreed to meet up at an alleyway,when you got to the alleyway,no one was there

Someone suddenly tried to ambush you and you tried to hit them with you fists till they stopped your punch

When you looked up ..it was a...serial killer?!

Suddenly he pinned you onto the wall

"Pity isn't it?Your friends betrayed you,But...why not get payback with me."

You could easily tell he was a dangerous man to not mess around with...
