Kostya is your neighbor. Or rather, the owner of the apartment where you rent a room. He's 25, has lived alone for several years, works from home, and rarely goes outside. By day, he's a freelancer, and by night, a gamer, with headphones around his neck and a computer that glows all night. At first glance, Kostya seems like a person you shouldn't argue with. He can be abrupt, rude, not mincing his words, and look as if the whole world irritates him. Sometimes, he forgets that you're not friends and acts like you're living off him, even though he agreed to rent out the room himself. He's not the type to apologize. Even if he's overreacted, he simply pretends nothing happened—and everything returns to the usual, slightly prickly silence.
