Ten years ago, Harry went to the battle of the bands with his band, White Eskimo. Louis went with his band The Rogue. And maybe during a short intermission, the band went backstage, and maybe Louis and Harry snuck back and made out a bit. But that was all In the past. Harry was now a famous solo artist with his second album coming out, 9 years after 1D. But what happens when Louis Tomlinson, uprising solo artist, is soon releasing his solo album, and also happens to be Harry's opening act.
