Serious version:
In the end of the world, mankind will perish, and you and I who are left will rely on each other and want to live this life together with you.
Ghost version:
Ms. Xu: Hello! Don't stand on the edge of the cliff and pretend to be melancholy. I'm still waiting to take on the important task of reproducing mankind with you.
Ms. Chen: Aren't I just drying my clothes? How are we going to make a baby?
