As can be discovered by reading older posts, this game used to contain explicit incest and lolicon fetishes. Because of Steam and Patreon requirements, they are purging these elements from their game (though rather poorly so far, in my opinion). Instead of your Mother, Older Sister, and Younger Sister, and other young girls in the game, all the girls have been aged up and their avatars resized to be adults. The family is now a 'family' that was very close to your family, where the Mom (Missy) wanted to marry your dad, and that for while you lived with them, before you and your dad moved away. Your dad disappeared and you came back to live with your pseudo-aunt and her daughters.
