They are to freeking cute

Well, it was cute but it could have gone longer with more details. It didn't really have that much impact on me as a reader. When you're using skipping scenes like, '10 years later' or 'when they turned teenagers' you're erasing off a potential attachment and build-up that a reader can catch and embrace. You could have added more details to make the audience more attached to the story and let it slowly build up until it reaches the climax of the plot (Chiyo and Kagome's reunion). Otherwise it would just be a pointless oneshot to me.

However, your story wasn't bad per se. That was just me talking in a more serious matter in terms. If you intended this as a fluffy oneshot, then you succeeded. It was cute.
