Supposed to Be (слэш)

It’s not supposed to be like this has been Steve’s mantra for most of his life. Nothing is how it’s supposed to be ー Bucky isn’t his soulmate, Peggy isn’t his soulmate, and now he’s seventy years in the future without either of them. He’s lost, he’s confused, and more importantly, he’s missing an integral part of himself. The bonus to all of this is that he finally meets his soulmate. The downside? His soulmate isn’t exactly pleased with their destined connection. In fact, Tony seems to be perfectly happy pretending it didn’t exist at all, especially after their first meeting and the subsequent truths that come to light.
Thankfully, Steve is far more stubborn than any one person should be, and he will do anything he can to make himself fit into this century ー and in Tony’s heart.
