1. Despite being among the "elites" in society, Kina finds it hard to relate to the rich and the famous. She grew up poor and lived on a farm, so she relates to the common folk much more easily and enjoys their company. Culturally, she's a catfolk through and through even though her family's on the mainland. It's not easy for her kind to integrate into other societies fully as they're singled out for being such a rare sight. A big thing in catfolk culture is their manes. They treat it as their "centerpiece", so Kina puts a lot of time and effort into maintaining it. She also stashes a small, emergency toolkit inside of it...and maybe a snack or two.
Jordeira isn't sure where he fits culturally as he's ostracized for many reasons, the major one being that he's undead. Necropolis is still in its infancy as a town, so the culture there is a grab bag of modern to even ancient customs due to the massive generational gaps between everyone. Everyone, including Jordeira, is in a transitional phase of their life. They're trying to figure out who they are and what their purpose is in a world that's unfamiliar to them.
2. Jordeira absolutely hates arrogance because it creates a lot of tension between him and the other person. Mainly because he also suffers from unwarranted arrogance. He also wouldn't like a partner who's passive and goes unnoticed by most. While there's nothing wrong with those traits necessarily, he finds it boring.
Kina wouldn't want a partner whose primary focus in life is wealth. Ambition is fine, but greed isn't, especially when the pursuit of coin comes before family and friends. She also wouldn't want a partner who treated animals and children poorly. Abuse being the most obvious thing there, but even treating them like they're nothing more than a nuisance is guaranteed to get on Kina's bad side.
