Memory Loss

A Once Upon a Time fanficion in which Emma Swan and Killian Jones, also known as Captain Hook, meet and find their forever lost love for one another. They go on many dangerous journeys, including defeating Hades and going back in time, and survive what no one else could. But one journey makes them lose all hope. Will they find each other in the end?

BTW:
I will start with a part in the middle of their relationship, and I will put in flashbacks. And it is mostly in Hook's point of view.
