Zarry - I can't lose you now (ON HOLD)

Based on the film 'The Vow'.
Zayn and Harry have been dating for almost two years now, infact, it as only five minutes to go before disaster struck. The two of them were in a car crash, and Zayn woke with brain damage. He remembered nothing about Harry, his best friends, or anything from the last four years. Especially about what happened with his parents... Can Harry make Zayn fall in love all over again?
