Since the world population is enormous each household can only have one child. If they have more than one child they have to fight to the death.
Anne it's your day to go out today.
Okay, Neli. Make sure to hid in the basement you don't want anyone find you.
I saw a very lovely man last time maybe I can catch his attention today.
Hello miss you look very lovely, would you like to go on a walk? My name is Cade.
Thank you, my name is Anne. I would love to go on a walk!
The Sibling Fight (TSF) is an organization that works for the government who deals with families that have more than one child.
Oh no this is bad, I really like Cade but I don't want him to flirt with Neli too. I should meet up with Bobby the head of the TSF.
I also had a fun day. I hope we can go out like this again.
I had a fun day, Cade.
Hi Bobby, thanks for meeting me. I actually have something to confess... I have a twin sister. She is hiding in the basement right now.
WHAT! We will come soon and don't worry I will ensure your safety.
HUH!
You're coming with us!
Since you both broke the rules I will execute you both.
That was a lie, I couldn't believe you actually believed it. You should've just kept your mouth shut listening to you sister who cared for you instead of sacrificing her to be with your lover.
LIAR, WHAT ABOUT OUR DEAL? YOU SAID THAT I GET TO STAY ALIVE.
