I'm looking for a stony soulmate au that is set post cacw where I think people have tattoos of their soulmate's first words to them or something, and Tony's is Steve but Steve has already met his back at WWII. In the end it turns out that Tony time travels and says his words to Steve in the forties... I think they were something like "it's true, there is some green in the blue of your eyes" or some similar thing.
Rings any bells?
Thank you all in advance
