Steve wasn’t alone when he went down in 1944. Y/N Barnes—Bucky’s younger sister—was on that plane too. When they woke up in the future, she stayed by Steve Rogers’ side through the confusion, the grief, and the years it took to rebuild a life that no longer existed. But while she stayed, Steve chose someone else: Sharon Carter. Y/N tells herself it doesn’t matter. She’s survived worse than being second choice. Then she catches Sharon cheating. And she says nothing—until Sharon starts getting reckless at an Avengers party, bragging about taking things with Steve to “the next level.” Some secrets don’t stay buried forever.
