Just got to chapter 5 and I've enjoyed my experience so far. I really wish that the incest with Carol was avoidable tho.
It's not incest. You adopted her, you're not her parent.
I also believe it is avoidable. I do not think you have to have a relationship with her. Although she and Naomi are undoubtly two of the best characters so not sure why you would but I do believe you can turn her down.
you can avoid getting into a relationship with her.
