Remember Humanity

She knows nothing.
He knows nothing.
However the human race is counting on them.

Earth has changed, more specifically human genetics has changed. Hardly anyone on earth is able to have children now. Humanity will die off soon if nothing is done.

Neither of them even knew their names when they first met, but now they're expected to live with each other. They are expected to carry on the human race, however will things change if they start to remember.
