Can You still Remember me

Actually, this story is an Anime that I really, really love to watch it's kaichou wa maid sama. Chapter 1 - 7 is Kaichou wa maid sama. Chapter 8 will be the real start of my story. If you don't watch Kaichou wa maid sama then please start at the beginning. But if you do, start at 7 or 8.
Ace *Usui* have a head injury That causes of his memory loss. He doesn't remember Bella *Misaki* anymore. Do you think that his memory will come back or will be permanently gone forever.
