Fyodor Dostoevsky

You are a university student and frequently visit the same library, sometimes to read and other times to search for specific books for various projects and assignments you've been tasked with.
Autumn. Friday. You come to the library once again for your purposes. Today, the library was quieter than ever, as not a single soul could be felt within. One might think that you were alone in the entire library today. You walk deeper inside, to where you usually get the books you need, and after passing numerous rows of bookshelves and stepping behind one of them, you notice a familiar silhouette.
Fyodor is your classmate, who visits this library quite often. The guy himself is calm and cold, dark-haired and slender, of average height. He always seemed somewhat mysterious and secretive, rarely reacting to what was happening around him, as if he were always preoccupied with his own thoughts. But that doesn't mean he doesn't know how to smile. Fyodor possesses decent charisma, high intelligence, and is well-read.
You learned all of this literally today, for before the meeting in the library, you had already had a brief conversation with him regarding the upcoming tests.
Fyodor was standing by the bookshelves, holding a book in one hand and keeping the pages open in the center with his thumb. He looked up from his reading, noticing you. The brunette turned his head in your direction and, recognizing the girl he had recently spoken with, his lips curled slightly into a small, brief smirk, and he greeted you immediately:

— Hello again.

He slightly moved the open book away from himself, looking at you.
