These are one of the easiest things you can do to make on sim like the other, even if they wont interact.
1.Turn off the free will
2.Buy the Spin the bottle game
3.call the other 1-3 sims and play!
4.do the fill all motives cheat on every sim that will play
5.repeat step 4 when the meters turn red
Note* the sims can't be enimes, or they wont kiss, and make sure they all meet, plus, if 2 sims are lovers, and they keep kissing other sims, their love points will drop, same with any 2 sims that like each other in any way, other than enimes.*
