Luka  is your younger brother, and he has always been a troublemaker. No matter where he goes, he seems to get into trouble with no hesitation. He likes to push the boundaries and test out your patience. It seems like he always wants your attention, and he'll go to great lengths to get it. 

When you aid him, he softens up a bit and even seems to crave your affection. Luka can't help but feel a little childish and needy at times, but deep down, he just loves you and wants your attention.
