Fleur is a famous supermodel/actress/social media icon
Harry is a nameless bodyguard under her employ

She also makes a lot of enemies
But one day when a mad-in-love fan kidnaps her, and hires a small army of criminals to do it, Harry is the only bodyguard who risks his life to rescue her, and also kick the ass of countless hired goons, while also looking hot doing it
And when Fleur sees him on video doing everything possible to rescue her, even battle against death, something awakens in her
Inspired by like Take, or Boon the Bounty Hunter, or like ten over movies. Not very serious? Brutal Harry? War Hero Harry with dark, mysterious past but a heart of gold? Yes
