(Inspired by a prompt from writing.prompts.re on ig)

Mark, 21, has lived a completely normal life for as far as he can remember: no weird encounters, no especially thrilling adventures, no dramatic relationships, no backstabbing friends; just a plain, simple life. Or at least, that's what he thinks. 

Reality is, Mark is so much more than your average young adult. He may not know it himself, but every single monday, Mark gets to chat with his best friend for a couple hours. Said best friend goes by plenty of names, the most known one being Death, but his personal favorite being "Donghyuck". Now, this by itself is peculiar enough; after all, not many get to be the Grim Reaper's closest buddy. However, there's one more detail that should be mentioned: Mark can never remember his encounters with Donghyuck. Every monday, he meets him for the very first time. And every monday, he forgets him in the span of a few seconds. 

Now, years have passed since the first time Donghyuck and Mark have met. Of course, Mark has no idea; but Donghyuck remembers everything, down to every single word spoken by his best -and only- friend. And, he's getting tired of being forgotten. So... What to do?

Surely, break all the rules of the Afterworld.
