There is always a problem Abyss Aether x Xiao [Aexiao]

The Prince of the abyss, and the protector of teyvat. Is, it a good match. Read to find out

The story is a mix of Genshin Impact x seraph of the end. I just love this crossover.

If you don't like, you don't need to read it.

In this story the seraph of the end character might not be included because I'm planning on using it in a different story.

So a small summary is that kazuha is aether and lumine's elder brother. So just read to find out.
