One sliver of doubt is all it takes to ruin something beautiful. But if that doubt turns out to be true it can destroy it. She thought that their bond was strong, that nothing could tarnish it. She believed in him for so long, hoping, that her doubt didn't turn out to be true. But alas he was a billionaire playboy philanthropist, and that's what billionaire playboy philanthropists do. I had gotten the inspiration from the song "Ciao Adios" by Anne-Marie. When I had looked up the lyrics they reminded me of Tony Stark and I couldn't help but create this. I know that this isn't really how Tony would act. Especially since he is very loyal to Pepper and loves her very much. I just couldn't help the scenario that went through my head. Also please keep in mind that I am new to writing angst and in general. I hope you enjoy and cry from the feels. (Y/N) = Your Name Lyrics = Bolded Italics Flashbacks = Italics Word Count: 3.1k+
