Who do you suppose would be the most jealous and/or insecure one in the relationship: Death, Puss, or Kitty? If any of them?

would it be weird to say that maybe none? none like how the "usual romance" handle it because god that's really been done to death (no pun intended) if there's insecurity, at least in this post movie context (since puss and death has sorta clear things up a bit in the movie and the character development already happened, after that they probably wont face or have quite the same problem, obviously), if it can count as one maybe there's some moment where puss can try a bit too hard sometimes? the rest probably is easier to explain when i got there but they definitely gonna have to adjust to each other....so yeah tldr probably puss, but not in the way you'd think (at least his would be the most visible)
