Seeking story of boy's best friend is really morphed amnesic woman.

Hi All!

Hope everyone and family are well. I'm searching for a story that might be an obscure oldie or a ancient BBS prattle, but I'm hoping for any leads. It's about two best friend little boys and for some reason one of them turns out to really be a woman from the future or another dimension or space who somehow lost her memory when she was transformed into a little boy to hide or spy here, and it ends with her (I think) adopting her best friend as his new mom or aunt or such. Sorry I'm so really vague here but it's one of those stories that you're not sure whether you really read or dreampt. I'd much appreciate any clues. You can also email me at [email protected]

Thanks and take care!
