AU Buffy & Spike forced to share an apartment

In this fic, Buffy and Spike work together I think, and don't like each other, or at least Buffy doesn't like Spike. Spike might be Buffy's boss; I believe she's his assistant. Angel works for the same company also. Buffy rents an apartment, and when she gets to her new place, she finds out the landlord rented the same place to Spike in some type of scam. They decide to just go ahead and live with each other.

Any help finding this fic would be greatly appreciated. Thanks in advance !
