I don’t really play the premade households on their own but my sims do marry premades quite often and then I end up playing them.
In my rotational save, I have sims married to Salim Benali, Joaquin Le Chien, Knox Greenburg, Travis Scott, Cassandra Goth, and Billie Jang. I also have a sim who’s engaged to Darling Walsh, a teen who’s probably going to date Rahul Chopra, and a sim who just went on a bad date with Cameron Fletcher.
In my legacy save, my founder just got married to Morgyn Ember and they’re expecting their first child.
