When you text the wrong number you usually say something like "oh wrong number sorry." But if that person happens to be Calum Hood, then he'll text you constantly, knowing he's got the wrong number and not care.
It all started with adding a wrong number...
M: WHY DOESN'T HE REACT?
M: LUKEEEEEE
M: COME ON BUDDY
K: who's Luke?
M: WAIT WHAT
M: U AREN'T LUKE
C: MICHAEL!! YOU'VE ADDED THE WRONG NUMBER AGAIN!!!
K: What? Who are you?
I'm going to warn you beforehand: this is my worst story ever. It's so bad you'll laugh your ass off about the clichés.
