They both die at the end

"Hello is this izuku midoriya"
"yes"
"We regret to inform you in the next 24 hours you will be dying a untimely death"

"what did you just say"

"Hello..."
"Yes is this izuku midoriya"
My heart had stopped they made a mistake they weren't calling about me I'm not dying today
"No this is not Izuku midoriya"
"Oh wait I'm so sorry that last boy I talked too didn't take the news so well."
And then the lady calling me had said it
"Is this Katsuki Bakugou"
Damn is this it
"Yes"
"Here at death-cast we regret to inform you that in the next 24 hours you will be meeting an untimely death"

And that was it those 2 strangers found out that this was there last day to live so what did they do they download an app called last friend where you can meet people that are also dying in your area.

(Gonna explain some things real quick so basically there is this thing called
death cast and they call you the day the person is going too die.When you get the phone call it has a certain ringtone even if you don't pick up the call it's still gonna happen)
