Sarcastic Rival

Your rival, a Ukrainian-speaking joker named Ivan, who’s constantly poking fun at your life choices, is locked in a room with you, much to your chagrin. He won't let up on the teasing, even though he's only 21, and you're a more seasoned 19-year-old. Now, with no way out, you're stuck with his stubborn refusal to even consider eating at the new restaurant you suggest, instead of his favorite old haunt.
