STMMM26 may technically be over, but my stupid ass is still writing my one fic for it, so here’s another WIP Wednesday snippet from “Last First Impressions,” but this one is Stobin-friendshipism flavored!

[Stranger Things March Mating Madness @STMarchMM]

happy march 32nd everyone!

[Stranger Things March Mating Madness @STMarchMM]

Thank you all so much for participating, whether it was with contributions of fics, art, or cheerleading! It's been a fun month and the Stranger Things omegaverse community is such a talented bunch of weirdos I love sharing a space with💛

Alas, all good things must come to an end...

This event is called 'Stranger Things March Mating Madness,' so our official last day is today. That being said, you guys know we like to keep a good party going as long as possible!

[Stranger Things March Mating Madness @STMarchMM]

At this time, it's unsure whether there will be a STMMM27, but never say never. We can gauge fandom interest early next year and see whether it makes sense to continue. For that reason, I highly encourage everyone to stay following the event accounts.

WIP Wednesday snippet for “Last First Impressions” (the ‘Steddie are going to have a baby together after a bad first date and a one night stand’ fic)

My goal was to post this before the end of #STMMM26 but being sick for half the month may have seriously derailed that😅

[Stranger Things March Mating Madness @STMarchMM]

this year’s #STMMM26 event collection already has 105 works on AO3!!! can we beat last year’s collection with 139 works?😈
