Yes, but if Emma and Perry do not hit it off, your roommate for the evening depends on your relationship with the other persons, which is even worse fuddling around to get right for this evening, so Holly can come over.
While Perry has grown even more annoying over the last couple updates, coupling him up with Emma, whom he has a crush on for years, gives you some good karma and helps you with Holly. Besides, Perry might start some personal growth now that he is with Emma.
And the two do something for the economy. Strap-ons and dildos might become a bestseller in Baluart now.
