Missing pool

There's a pool for a Genshin Impact comic that I'm 100% dead sure remember seeing on Danbooru, but I can't find it again, which surprises me, I though even deleted posts left traces. The name was something like "what if the travellers acted like real siblings", and it was all about Aether and Lumine bickering, backstabbing each others, and laughing at each others' misfortune.
I don't remember the artist name, and I think, albeit I'm not sure, that it was directly in English, and not in Japanese or Chinese.

Such a comic does exist and it is in a pool, but it's a two-page comic in part of a broader pool about family troubles. In fact, there are multiple with similar themes.

It was a lot shorter than I remember, but thank you so much, I've been looking for it for weeks now! Thank you!
