Also, I'm quite new to these definitions of housemates instead of siblings and the landlords instead of parents. Is that how they are viewed by the characters or that's actually the case now instead?
Cough there is a mod floating around on the web, you can find it on lewdpatcher or on F95Zone that reverts some changes I had to make to the game to have it be allowed on Patreon.
I AM NOT AFFILIATED WITH SAID MODDER AND DO NOT CONDONE HIS ACTIONS.
