Buffy enters a portal to the past and meets Spike as a child.

Hi, I need help finding a fic where Buffy enters a portal to the past and meets Spike as a child. He thinks that she is a fairy warrior or something like that. He even writes her a cute poem. They then meet up in an altered School Hard... I think the story might have been a little old...

Thank You!

I love that story, this should be it:
