Harry's one of Hollywood's biggest actors, has made a name for himself in prestigious films and lives the life of a superstar. There's just one thing missing to make it picture-perfect, but the one Harry's in love with is completely out of reach for him. Enter Louis, one of Hollywood's biggest actors himself, who just came out of the closet and taps new genres in the industry. When Louis sacks the role Harry auditioned for in Scorsese's next big film, their irrational feud starts. Who could have guessed it would get even worse when for promo season, their teams decide to present them as a couple for publicity? In short, Harry's in love with someone and doesn't care about dating anyone else, Louis never felt home in L.A., Liam writes love songs for someone he shouldn't write love songs to, and Niall makes everything better with good food.

This is NOT my story all credits go to dolce_piccante on ao3 - In the grand scheme of things, finding a date for a wedding should be no problem for Louis Tomlinson. He's rich. He's handsome.
