Gu: The distance between us is too big, like the distance between a bird and a fish... I will never be able to reach your world. Just like your names and mine, one is in the sky and the other is on the ground.
Chu: What does it matter if you can't arrive? It's enough for me to come down and stay with you.
The male and female protagonists are clean physically and mentally. If you don't like it, don't enter.
