Zayn and Louis Have has a good thing going for a while now. They were happy. Key word were. Management found out and were not happy with it at all. They told zayn that if he didn't leave the band without any explanation to the other boys then they were going to make sure louis' life was hell. Zayn then left and didn't tell any of the boys why. It isn't till many years later that zayn tells a mutual friend and things come out, but that isn't the end.
