Tony Stark REALLY hates magic with a passion. He knows it's got something to do with how his memories aren't quite as he remembers them. He knows Steve screwed him over and sent him that shitty apology with an even shittier phone. And he is pissed supposedly with no end in sight and no resolution to be had. And yet, he also has this other set of memories - One where he is madly in love with Steve...
Steve Rogers REALLY feels like things with Tony could've gone a lot better. So he stubbornly stays in the Avengers compound to try to set things to rights, vowing to repair his Avengers family and his friendship with Tony. And yet, his endgame is still to help Bucky get rid of the Winter Soldier programming - Help his first and the one true love of his life to find himself again...
Bucky Barnes REALLY loathes having to rely on others to tell him about his life. Steve is a big help, but sometimes, Bucky feels like Steve's after helping him for the benefit of the person he used to be rather than the person he is. Unlike Steve, Tony doesn't give a shit about him. And yet, it's with Tony that he feels like he can be or do anything - Like fall in love with the man he had orphaned all those years ago...
Tony was a little older than average when he found his soulmate. Because his soulmate didn't exist on this planet until he came through a portal from a different dimension.
Imagine Tony getting deaged into a 5 or 6 year old, but instead of the team finding him, Bucky, still on the run and struggling with himself and the winter soldier, does. Bucky tries to take care of him, learning of all of Tony's issues and the abuse he went through. Eventually he has no choice but to come in and bring Tony to the avengers. After Tony comes back to himself they deal with the aftermath
Tony really hates magic. Has he mentioned that lately? He really, really hates magic. Nothing ever good ever comes of it. What he hates even more than magic? Portals. So when the two are combined, he really isn't happy. His point is proven when said magical portal spits of not one, but two, different versions of his father along Ana and Jarvis, young Aunt Peggy and his Mama. Things get... a little bit... interesting after that, shall we say? This may be a blessing in some ways, but it also a curse. It ends up being something else too - a way to finally lay some of his demons to rest, maybe.
