An Amnesia Romace

One day, a girl wanders to a pond and remembers of her and that boy that she loved. But, unfortunately, due to a crash, the boy forgets about all his friends, and the college school year. All he knows is his family, and the high school education. The boy moves on, and still wonders about who that girl was. The boy looks toward the future, while the girl looks back at the past. Can fate twist them back together again? (Might consider a sequel/prequel/trilogy)
