Do You Still Have A Soulmate When the Marks Are Gone? (слэш)

Tony knew at a young age that he wasn't going to grow up meet his soulmates and live happily ever after. Why? Because they're dead. They died years before he was even a thought. Steve and Bucky died heroes and Tony is just Tony. At least that's what Howard says. He spent years hiding his marks from prying reporter, then Afghanistan happened and his soul marks were replaced with the arch. Now it turns out that Steve is alive and can't remember the name of his third soulmate and the mark is too damaged to make out, which is fine. Tony knows how to hide things. He'll just hide the fact that they're soulmates. No problem. Tony knows he can't compete with a ghost...oh look Bucky's alive too. The universe must really hate him.
