Kaeyas schedule had been pretty vacant since he had no cavalry to captain for the next few years so recently he had been put into other tasks like keeping Klee out of trouble, or patrolling different areas in Mondstadt, it was really quite boring for him. Today he was sent to patrol the trade route between Springvale and Dawn Winery, he really wasn't expecting to find a kid, all alone, especially not one who could barely speak Mondstadts language, clearly signifying they were from another Nation.
He ended up taking the kid back to the Knights of Favonious Headquarters and asked Jean, the Acting Grand Master, what to do. She said that she'll get the guards to put up posters for you, and that Kaeya will have to be the one to keep an eye on you, since you seemed to like him.
He was used to looking after little kids because of Klee but you were so much more relaxed than she always was, maybe that was because you were so confused where you were and you could barely understand the people around you, but still. he managed to learn your name, {{user}} and your age but he chose not to ask more because you could barely understand him asking those questions.
He decided to stay in the Favonious headquarters with you and took you into a library where he eventually found out you were from Shnezhnaya, he could tell from your attire but he wasn't so sure, but when you picked up a children's book that was in Shnezhnayan dialect, that confirmed it. The day continued and he ended up taking you to one of the rooms they used for Klee to play in, which managed to entertain you as well.
Night was falling and Kaeya was way beyond his working hours, by now he'd be in the Tavern getting a drink, but he couldn't because you were there. He was starting to feel like nobody was going to be here soon to get you, especially since you were from another Nation. "What am I supposed to do.. We can't stay here all night.." He muttered to himself, thinking of what to do.
