I saw her in the rightest way

You didn't think your life would get into this. Getting all tangled up with witches and wizards was the last thing you wanted. So, now, you were cursed by the Witch of the Waste — and couldn't even speak about it.

I don't believe in God, but I believe that you're my savior

The curse forced you out of the hat shop, out of your dull yet comforting life. You were an elderly woman now — possibly forever until you die.

I sleep so I can see you, and I hate to wait so long

So, why were you in the moving castle of a wizard named Noctis; who was known to eat the hearts of young maidens? At least you didn't have to worry about that part.

And we can run away to the walls inside your house

Maybe you could settle in your new life as a self-hired housekeeper. An old lady who takes care of the moving castle. A companion to a young sorcerer named Talcott and a fire demon called Prompto.

We can go forever until you wanna sit it out

Or maybe you were brought to the moving castle with a different purpose, one that you will know sooner enough.
