The keep stacy choice for sophia questWhy? There is a perfectly fine questlog in game, including an app to locate the girls.
There also isn't any huge drawbacks in picking the "wrong" Choices. Most of the time it just means that you need to use your powers in the open world to further corrupt the girls. The only missable I can think of is the sex scene in the fantasy world, but it should be clear what to chose when it happens.
I am confident the lack of a WT/mod is the lack of need for it.
some choices do effect game, its neved clear about it.
