The wishes the parents made

"And there is Alfredo, in the middle of it all. His little sister made a wish when she was dying and she was specific. She probably started it all.

If I don't go back, I'm to be his mate, and look at me, you call me a little girl. I don't blame you. I stopped growing physically.

It will take me about ten thousand years more to look like your mate. By then, Alfredo would be dead. So I need to leave so I can match him with someone else.

His sister, well, you can't blame her. She was a little girl and only watched cartoons and read them so her wish was that her brother marries an angel with white hair!" She laughed before continuing,

"she went on to describe the Angel and it matched with who I was. The moon goddess matched me with him. And now I had to be foolish enough and mess with you all and get punished to come and live here."
