I’m looking for an au in which Tony lives in an apartment across the hall from a couple (I think Loki and someone else maybe Bucky or strange?) and one or both of the couple is a lawyer. And Tony is dealing with a difficult ex (maybe Steve or Stane). So the Tony and the couple pretend to be in a relationship together to help him deal with the ex. I don’t think it was finished, at least not when I originally read it, but it did have a decent amount of chapters.
Sorry, I know it’s not a lot to go on considering I’m not confident about the characters in the relationship, but hopefully someone knows what I’m talking about haha
