Slipping off the Page into Your Hands (слэш)

Soulmates have their first words to each other written on their wrists. This should make it easy. For Steve and Tony, it is anything but. Steve's problem is that the future he has awoken into is nothing he was ever expecting: he has a soulmate now. Who might be a robot. And if his soulmate is Iron Man, how can he be so attracted to Tony Stark? It should be impossible. Tony's problem is that he is Iron Man, his soulmate is a man whom he in no way deserves, and he is going to fight everything in his heart and do his best to make sure Steve never, ever finds out the whole truth.
