You could easily twist Jozef's tendency to call people around him terms of endearment, like szivecske, kedvesém (hopefully spelled it right) and other terms as him coping with loneliness to some extent.
I would not call him a completely lonely character, like Pavol or Matej, tho the thing is that the main duo are in a way self isolating characters. Matej's place in the castle is the castle chapel, he doesn't belong anywhere else in the game (we do know he's a monk in the Debrecén monastery, but that's not an area in the game and also it's pretty damn far, like, if we just pick the closest major town in Slovakia, being Košice, it's roughly 2 hours by car, tho of coure, you don't spend all 2 hours in Hungary as Košice are further from the border, I am just too lazy to figure out which town along the border is closest to Debrecén, so I picked Košice. By foot it's 2 days if you would like to know). And Pavol is a drunk so not many people want to be around him and also depressed so he's self isolating. Also he doesn't seem to be a social drinker. I will talk about it some more one day in a post stuck in the draft purgatory.
Jozef on the other hand seems a lot more social, even if in his own way as the literal landlord, as he does occasionally command people, when he wants someone to play a board game with him, tho it's usually either because he's already pissed about something or when it's Pištík specifically. Otherwise he just asks politely and I can't help it, but read his line, where he asks Matej and Pali to play Mariáš with him in the same tone one would give a character making puppy eyes at someone or when saying like "Pretty please?"
Dude is a little lonely probably, or just really likes boardgames, which is something you really can't play alone. I don't think he is a pathetic guy in that sense, he really just... Likes being around people and definitely doesn't have a hard time forming attachments and that's beautiful.
