I was never a person for romance y/n fanfics so mine may be a bit odd but I digress.
I made a universe in the past but never went through with it so its a free concept but it's a bit complex, I feel it's a lot like that tik tok as it has a dark kinda sinister theme to it. You can edit everything how you would like, this is just the way I created it
An Idea could be that you can take one group and assign each member or groups of members to a district instead of whole groups per district, it would make things easier
