Years ago, in the car.
Two women clinging to each other
"Sister, my son will be called Nanchen from now on, and your son will be called Beihai. We want the world to know that no matter how far the distance is or how deep the prejudice is, the stars in the south can still light up the sea in the north. Our children will live happily together in the future!"
Years later, in the sea of fire.
Two teenagers clinging to each other
"Brother, don't feel guilty about what happened back then. How could the stars in the south light up the sea in the north? How could such a dirty me be worthy of such a clean you! Forget me. I'm sorry."
