This game has 3 types of LI's.
The main 7 that you can't opt-out of.
A bunch of secondary girls, that have a lot of content, BUT, you can opt-out of for any reason.
And several girls that have only a handful of scenes and can be opted out too. Like Brandy, Betty, Zelda, Shawna etc...
Fiona and her family are on the second level. These girls are mostly grouped in family harems that will have minimal (if at all) contact with the main harem. Sorry for the sad news, but this isn't a giga-harem game. Just a multi-harems one.
MoonBox can I ask again for a background color scheme on the Relationships page? Thanks.
Peace
