I recently started rotating between households. Currently in my game, Summer and Travis are dating and new parents. Liberty has moved into the house across the street, and is dating Mitchell Kalani in Oasis Springs.
I didn't really plan any of that happening as quickly as it did but Wonderful Whims, MCCC, and a few other mods decided for me.
Now, I'm playing the Free Spirits (Maaike Haase and Ulrike Faust) household in Windeburg. Maaike has a crush on Gunther Munch, again Wonderful Whims, and Ulirke has a thing for Darrel Charm. I'm not sure where either of these crushes are going to go yet, as I haven't played the other households.
