good day thank you for your feedback, at the time of writing the idea was to have the time inbetween the appocalypse and the happening in the story to be circa a year, but I will most probably rethink it in the finished version of the first chapter, most probably to 1-3 months.
I still struggle a lot with characterising characters in my writing. I wanted with Lea to go into a direction of a serious mature (in mind) character which shows her childish site especially by complaining. but I will nonetheless try to work more on it as well, to make it feel more organic.
