In a universe where you can make contact with your soulmate by drawing onto your skin, Bucky's soulmate immediately stands out. It doesn't bother Bucky too much his soulmate puts them in places where only they can see, the drawings are for him, and that's enough. They are so much more complicated, more detailed, more beautiful than the ones others get, after all.
One day the marks on his skin are not drawings, and they mark a pivotal change in their relationship. A change that ends with Bucky being disillusioned and enlisting. The loss of his arm overseas is just a step above the rock bottom they must reach before it gets better.
This is a story about two soulmates, lost and broken. But aren't broken things more beautiful for the cracks?
5 times one of the Avengers saw a gap in Tony's mask and 1 time they didn't. The Avengers realise they don't know Tony Stark as well as they thought they did.
Tony takes the bullet meant for Captain America at the end of their war and through his death, brings together the team again. Only, he isn't really dead and when he comes back, the equations between the team-mates begin to alter and reform, writing a new story altogether.
