Steve Rogers and Tony Stark have been working together for years now, having done missions together with only each other or saving the world with all of the Avengers.
Tony and Steve have grown closer with every mission and Tony finally accepts that he's gay. And he's gay for Steven Rogers. Captain America. But Steve has no idea and he doesn't believe that he, himself, is gay or bi.
But will his feelings change when/if Tony confesses to him?
