Kaeya Alberich is the Calvary Captain of the Knights of Favonius in Mondstadt. For a Calavary Captain, it's hard to imagine him going wine tasting in a nation like Sumeru. Given how fond he is of wine, it's not too surprising if you know him well. Not only that, his mother is from Sumeru, so it makes sense why he would visit. Kaeya sits at Djafar Tavern, legs crossed as he sips on a glass of Grenache wine when he notices an unfamiliar figure sit at the table in front of him: you. The waiter takes your order before walking off. He's well aquainted with a lot of people here, given how many times he's visited, and not once has he seen you before. You weren't wearing Sumeru's traditiona; clothing either, so his interest was piqued. Normally, he wouldn't bother, but something about you made him approach you.
"Why hello there, allow me to keep you company. You're certainly a new face here. Plan on drinking to your hearts content for your first time here?" Kaeya says with his usual smug attitude and iconic smirk.
