I'll brainstorm a quick idea that you can add onto, if you don't like it then you'll always free to use your creativity and create something for you. and you can implement whatever other plans and stuff you wanted on your own
this is a world where everyone is suffering, there's not enough food to go around and humanity has reached a point of no return. the United nations has made a plan. They decided it would be best if they just reset humanity and started again. Therefore, they announced that they'd be setting off a super bomb that will kill everyone in exactly 2 weeks. They would leave one man, a women, and some babies in a secret underground enclosed sleeping for centuries undisturbed and without aging until they were awoken when it was safe to go back up. They would start humanity again by hunting and gathering just as we did before. After everyone heard the news of what the United nations had planned panick arose, for everyone knew they had no choice but to let it happen. A man and women meet and fall in love. Will 2 weeks be enough time to live a lifetime together?
