[Yuan Gu] Gu Qingpei's Birthday and the Tenth Anniversary of Yuan Gu

Happy birthday, Qing Pei, and happy tenth anniversary to Yuan Gu.

This is basically a rewritten extra for Jealousy. I decided to write this birthday story too late and didn't have many ideas. I just couldn't let go of Jealousy, so I reworked it.

The story is now complete~

But there are still details I can't help wanting to change. They're just tiny issues with the wording here and there. If I don't fix them, they'll keep nagging at me, but you don't need to reread it. You'll only be left wondering what changed. So please ignore the "edited" notifications. Sorry for the interruption, and thank you.

Theme: Yuan Gu are a match made in heaven, together forever.
