The Death of Calum Hood: Cake fanfic

My name is Calum Hood and im dead.

Life has really changed since Calum came back from the dead. And so has Luke's social life. "He has become an antisocial creep." Some of the people around him say. Well yeah, they're kinda right. He hasn't been talking to Michael or Ashton for months now. Or maybe evens years. Calum is also really quiet these days. So quiet you'll feel as if he's dead. He is... All Luke does now is research about how people can be resurrected. Oh! Speaking of that, he's found a book that might be of use to him. It says that "once you die and resurrect, if you die again, you'll face a terrible afterlife". He doesn't want that to happen to his best friend. Calum walks into the room only to catch Luke reading that exact book. "Luke!" "What is it that you're so into all this resurrection stuff, you know it wont help you with my problem."
Luke: I have the slightest feeling it will.
Calum: *now understanding* okay, i get it, so you're trying to help me have a better afterlife.
Luke: yes Cal, you are right. That's pretty much it.
Luke said goodnight to Calum, went back to his room, and switched off the light. He got into bed and thought about what he read.
