Let’s put it this way, anon. As far as my muse is concerned, Tony is Tony. Each Tony she meets is the only Tony, because I do everything AU unless I’ve a reason not to. I’ve tried to make her not be in love with him, and it just does not take.
Me personally, I really like billionaire-tony-stark’s writing. I want to write with that person, because they are just awesome. I frankly could not care less if his/her Tony reciprocates Summer’s feelings, if they superhero together, if she becomes his PA or babysitter or weird friend or drinking buddy or whatever. That mun is a /superb/ writer, and I want to work with them. Whatever it takes.
