In fact, I'm currently preparing to release a short fanfic about Kaeya, who was given a teapot of serenity.
English is not my native language and I am writing through a translator, but why not try?
The idea of the fanfic is that Kaeya, although he has a house in Mondstadt (maybe rents a small apartment across from the Gete Hotel), still doesn't feel like it's his home after he was kicked out of the Winery Dawn . Like, he can buy it, yes, then no one will kick him out, but he still doesn't know the future, and is afraid to ever leave it because of the reaction of the Mondstadt residents to his Khaenri origin. But the Teapot from the Travellers is really his thing, his albeit magical, but home, which no one can invade without his consent or permission.
Over time, he will arrange it for himself and will start inviting his closest people there, starting with Klee and ending with Tartaglia (I believe in their crazy, but friendship). It will be funny when Diluc learns about Kaeya's "house" from his friends, and Kaeya himself will be afraid to invite Diluc there for a long time because of their past (they are brothers, no ship). Slowly revealing Kaeya's feelings, realizing his value and love for his friends, and a little angst with a change of abode, where he experiences his dark times without letting anyone in, and then returning back with a smile on his face.
I hope I can make an interesting story and I will share it here. If you have any thoughts or ideas about this idea, we can discuss them together!
So, I just love Kaeya and his comfort. Bye-bye! 💜
