Forgotten promise [GxG]

"do you promise to marry me when we grow up?" the eight years Brittney asked

"i promise!" promised the also eight year old Alice

That was their last conversation before they separated

a few years later, one remember the promise and looked forward to it, while the other forgot and doesn't even know about it.

Or did she?

what happen if they crossed paths again, and when one find out that the other doesn't remember their promise, what will she do?
