Heartache On The Big Screen (Larry Stylinson)

Harry Styles 23 and a single father.
Louis Tomlinson 25 and single.
Both are two very famous actors who have never starred in a movie together, but plenty separately. Both openly gay, star in the a new up and coming movie about gay love. It's no surprise when they fall in love both off and on screen. But with that, comes the heartache. Will it be on or off screen?
