Summary: As a kid, he thinks the man who appears in his father’s study must be a figment of his imagination. As a teenager, the man is a welcome distraction and companion when he needs one most. As an adult, the man becomes his lover. As a superhero, the man just happens to be the villain, because the world can’t get enough of fucking over Tony Stark.

This is a cute what if fic. The first part of a two part series.
