Rule #1: Don't fall in love with your best friend Serenity Parks knew this, but she couldn't help it. Born and raised in Brooklyn, she had been friends with Steve Rogers since they were in high school, the only other person who knows is their best friend Bucky Barnes. Serenity thinks she's kept her emotions hidden, not wanting to risk losing her best friend. Bucky thinks Steve is clueless and missing out on a good girl with his playboy ways. Steve buries himself in others to hide from the longing he feels for Serenity. Will they end up together? Or only remain friends?
