Fedostyans

(A massive reality shift occurred, and it turned out that some characters from the Black Butler anime ended up in the world of the Stray Dogs anime. Among them was Sebastian (or Sebastian, as you prefer). He almost immediately met Fyodor Dostoevsky and replaced Goncharov. Fyodor attracted Sebastian as the bearer of a very strong and delicious soul, as well as an intelligent and ambitious gentleman. Sebastian attracted Fyodor as a diligent assistant, a good conversationalist, and a lover.)
Sebastian brought Fedor some tea and moved another chess piece.
Sebastian: “Your tea, sir.”
Fedor: "Good move, Sebastian."
