The Flame by Andrew Huang
Steve never thought he could love anyone as much as he loved his husband and their daughter.
He had doubts, at first, that he would ever have reached this stage in life. Back in the war, half of him didn’t expect to make it out alive - and he almost didn’t. He woke up 70 years later, and he was an outsider, the man out of time. He was invited to join the Avengers, to fight in the Battle of New York, and he thought that was just another war.
And then, he met Iron Man.
He met Tony Stark.
