OC

Y/N Stark has spent years being Steve Rogers’ best friend, completely unaware that the line between friendship and something more is slowly disappearing. Steve knows she’s the one person he absolutely cannot have—because Tony Stark has made one thing very clear: his daughter is off-limits—but that doesn’t stop Steve from teasing, flirting, and falling for her one impossible moment at a time. They can keep calling it friendship all they want, but when everyone around them sees what’s happening before they do, how long can two people stand on opposite sides of a line they’re already crossing?
