Help with fanfic

Hey! I’m sure this is a weird request but I’m currently writing a fanfiction about Suho’s recovery journey post Season 2 and I keep hitting roadblocks about pacing and characterisation. I was just wondering if there are any other fic writers out there (or people who genuinely just enjoy chatting about the show) that I could talk to. I don’t have any friends that have watched the show or read the manhwa and though they’ve helped a lot, they don’t really understand the intricacies of the characters. It will be a SHSE pairing and features some pretty bleak descriptions of mental health (in a respectful way) so I’d say it’s only suitable for 18+. If you have a fic I’d be more than happy to beta/brainstorm/be a sounding board in return!!
