Can you please tell me how to get Amari route?
Essentially, you have to treat Konstantin only as the customer, then the Fox man (I forget his name right now) only as your co-worker. Somewhere along the options I also chose the "call your ex" option, I think? Then the vampire arrives and soon after Amari. You then are nicer to Amari than to the vampire and you're on Amari's route now :)
