An Old Promise Broken (and A New Vow Made)

*SPOILERS FOR SPIDER-MAN: NO WAY HOME* He had broken his promise. He had made a choice that wasn't his to make. And yet, she still came back. This is my first ever fic, so the characters maybe a little bit OOC. So please, be kind, and any constructive criticism is much appreciated. Thank you, and I hope this helps you as much as it did me to numb the pain of the ending.
