can i read this before mayday?

Probably not. This story is a continuation of their relationship in Mayday and I think you need the context to understand the struggles they have in this story. Plus, they also reference characters and backstory from Mayday.

I read it before mayday LMAO u kinda get the idea since they repeat multiple times / give a summary of what they r and all. Plus it's short so it works out.
Honestly just think of this as a story that already has world building and explains it thru context clues
