Twisted [Zouis]

Louis was Zayn's best friend. He "died" in a fire, or so Zayn thought. After the loss of his best friend, Zayn changed. He became cold, callous and calculated. To top it off he charmed his way in and out of things effortlessly. You could call him a sociopathic psychopath.. He gets admitted into a mental hospital when his boyfriend of two years, Niall, finds him unconscious for the third time that year due to suicide attempts. What happens when Zayn sees Louis again, but Louis doesn't quite know who he is?
