Zhu Xingzhi and Ji Lanyu were originally from two different worlds, so logically there should not be any intersection in this life. Who made the two of them see something they shouldn't have seen, and their fates have been entangled ever since.
Zhu Xingzhi: Actually, I am innocent. Isn't it bad to travel, eat, etc.?
Ji Lanyu: Do you think I really want to be with you?
Intention: Even if the beacon fire burns out and no one responds, we will ride on the border and share life and death.
