One battle. One day... Steve Rogers was the only Avenger to die in the battle of Thanos. As always, Steve had gone out a hero, saving his friends, the citizens of the entire world and, saving the girl he loved-Natasha Romanoff. Five years after his death, Natasha still mourns for her loss and has perfected the art of hiding it, especially from her fellow Avengers and her son James. Believing that his death was entirely her fault, she cannot allow herself to move on and continues to dwell on the past. But when Natasha helps a mysterious old woman out of a situation, she gives Natasha seven chances to change the past. Suddenly Natasha is in a race against the clock to not only save Steve Rogers, but the fate of the world as well. "If it was the other around, and it was down to me to save your life, would you trust me to do it?" "I would now, and I'm always honest." --- A/N: This will be set post Infinity War and since I wrote this before Endgame was released, all characters and predictions/theories used were my own predictions for Endgame based off MY plot. The story is mine but all the characters belong to Marvel.
