Option 1: they live in forgotten hollow but take lots of vacations to different worlds
Option 2: they live in mt komorebi in haunted japanese house the lady still gets her outdoors life but theres spooky stuff to keep dude happy until the night
option 3: they live in sulani but dude gets creepy basement to hide from the sun during day or they live in shipwreck or something of the sort
option 4: they both move to some other world that they have yet to explore and explore it together
also I think creepy church theme would still work in say windenburg or tartosa if forgotten hollow is simply too dark for the lady
