Fandom PSLs

So I've been drowning in Marvel Cinematic Universe soulmate AUs lately and was hoping to get a line going. Can be short to long term, depending on what we decide to do with it. I've got a few vague ideas in mind depending on the route taken. Pairings can pretty much be any ship in MCU. Soulmates can be any sort really, from the physical "imprint" version to the tattoos that count down or say the other person's name or has their fingerprint, etc. Slash only please.

dying to write something for my natasha romanoff or darcy lewis. i'm looking to brainstorm fun, possibly long term ideas. het and gen welcome as well as possible crossovers.
