I cant figure it out as well. I did manage to get 2 of the 4. I got amber in the bunny and witch outfit. These images are tied to certain girls. But cant figure the other 2 out. So any help is appreciated please.
first thing I did was go through it again and choose the opposite options, another thing I did was only focus on 1 girl and not all of them. So far that is all I got is 2 out of 4.
