Five years of pain, five years of suffering, five years of regret...

Louis and Harry had 5 years of happiness before everything went south. Not much but regret, hate and bittersweet memories left between the two of them.
Silence. Almost total silence for five years . Before they are forced to smile, laugh and talk again, all in front of the cameras. And it went great, in front of the cameras at least, but behind the scenes, Harry was not the same person the boys once knew.

The fans got everything they wanted, a reunion, whilst the boys got forced into dealing with past problems and repairing old bonds.
