Square R3: A Cinderella Story (слэш)

Tony Stark comes home from his parents' funeral to find out that both he and Stark Industries were on the brink of bankruptcy. After months of slaving away trying to save his family's company, he decides to let himself have one night of fun at a masked ball to benefit military veterans.
Bucky Barnes doesn't know much about the sexy stranger from the masked ball, except that his name is Tony and he has an ass that makes him want to get on his knees and give thanks. When he ends up with the man's cell phone at the end of the night, he hopes that this will give him a chance to learn more.
