I dont understand? Is this like a backstory or what?

i think it might be the directors side of the whole story

i assumed it was like an alternate universe type side story.

Yes this is the backstory of how they met & how the director fell for him & started giving him coffee everyday which we already witnessed in the early chapters ya know

if u read extra 1, it wrote there that this happen before the first chapter which mean this is just a backstory from the director's pov

Okaaaay, thank you guys
