Let me introduce the Balkans

I just had that idea. (also I couldn't find a cover picture that fits)
Ask or dare them anything, from their crushes to who's the oldest to their favourite food. Anything!
Countries:
Blood-related - Yugoslavia (father), Croatia, Slovenia, Bosnia and Herzegovina (I imagine them as two separate people, sorry), Macedonia, Kosovo, Montenegro, Serbia
Non blood-related - Bulgaria, Romania, Greece, Albania, Türkiye
