Hello, Stranger

From their very first date, Jamie and Lucy know they've met THE ONE.
They're as different as night and day. Jamie's a home bird, while Lucy's happiest on holiday. He has a place for everything - she can never find her keys. Yet, somehow, they make each other happier than they ever thought possible.
So why does this story start with them saying 'goodbye'?
And does this really have to be the end. . . ?
