There was interference from prude and shit people to create a nonsensical path where she forgets everythong about the first chapter.... a call this path "Anna the brianless doll with a fake amnesia"
fortunately there is the ways to corrupt (again) her by making choices to make her remember what she had done with the all men in chapter 1
basically it seems that the wounding of her beloved boyfriend (whom she made cuckold at every opportunity with great pleasure) and the kidnapping of her sister and caused her amnesia...but just of the “Anna remembers what she did” and follow the path of the male doctor and Jeremy alive...that you will have the continuation of chapter 1 after Andrew returns to form
