Why can't I get the scene when I call them. From Jessica and Kaley, she says she needs to improve the house.
You need to spruce up your house.
Here's what to do:
(1) Visit Estero Park, walk about and collect talismans and coins.
Tip: Retrace your steps moving forward and backward between locations and save your game regularly. Doing this can spawn more artefacts. Visit Doctor Jessica of an intelligence boost or Pricia for an awareness boost, to enable you to see/find more loot, although this will cost you hard earned money or treasure.
(2) When you have collected as many talismans as you can go to the library and sell them to Diana.
(3) Go to Squallmarket and buy the cheapest thing available, whatever it might be, from the home improvement shelf (first left as you enter the store). If you don't have enough money to be able to buy anything repeat steps (1) and (2) until you do.
(4) Booty call Kayley or Jessica and see if she will enter your house.
(5) If she enters, enjoy, if she doesn't repeat the process from step (1).
Eventually you will accumulate enough possessions or have done enough improvements to win the lady.
(6) Don't fuck up your game by resorting to cheats and/or mods; gird your loins and be a man!
* If you are good at fishing do that as well if you feel like a break although I'm still trying to catch a 29 pound rockfish!.
