How Often Do You Play With Occult-Human Sim Couples In The Sims 4?

For me, playing occult Sims adds more to my game than doing the same old regular stuff over and over. I don't start a new game with this in mind, it usually just happens. The game I'm playing now has a Spellcaster involved with a rare game-generated young adult Prime Vampire who just ranked up to Master Vampire. It's been an interesting game so far.
