I have a mansion the biggest free home you get in game.
I just upgraded my girlfriend to Aoi (the sixth one, 6th)
What I wonder over is the 7th girlfriend Miki, it says on the upgrade screen that you only need a mansion but she is listed under manor so do you need manor to get her or not?
If you cant upgrade to her anyway so does it seem wiser to just sell the bikinis (not spending 3k on a better home)
