For those who are wondering, I have a Geoanemo family AU, born just cause I thought that the interactions between my genshin mains were fun. In this au Xiao has a twin, Alatus, an oc i made from Xiao's beta design, and they are guili/zhongguang's children. From a misunderstanding, Xiao and Gorou think Noelle is something like a god warrior so they start following her trying to learn to fight from her, but she's actually only super strong. They all became friends and they have their little adventures, but Xiao and Gorou sometimes fight, nothing to worry about it, just some cat vs dog fight to have their master's attention. Oh, I forgot to mention that in this au Xiao, Alatus and Gorou can shapeshift and turn themselves into animals. Also in modern au they live together and share a flat. I also have a witches au where they all are Noelle's familiars.
The dogs here are Tawara (Gorou's camp dog from his bday art) and Shirou (his family dog, the one in his burst).
