Playing the last time I only had the Grace Threesome Ending, so I guess it depends on the promotion, the fear/love route and i guess some questsI haven't played this in a long time, and it seems you can make amends with the girl you didn't promote now, and even get endings with her.
My question is: My savegame is on the Izumi path, and I have a marriage and children ending available for her, but "only" a lust and threesome ending available for Grace.
Would that be the other way around if I chose Grace earlier in the game, or are all endings available no matter who you chose?
