It is love. "Lamp to Shine Rivers and Mountains" mentions the "married life" of Chu Ci and Han Er. Han Er still has a strong and paranoid love for Chu Ci, and Chu Ci is very lonely. , he longed for love. After a series of revenge, Chu Ci was also tired. Looking back, there was still Han Yue who was really good to him in the world, how could he not be moved.
The contradiction and hatred between Mr. and Mrs. Han Chu are not as exaggerated as many people describe. If the two of them didn't have the incident like Han Qiang's car accident, then they were simply robbing civilian men. Chu Ci should have hated Han Yue from the beginning to the end, as he himself said: If your surname is not Han, I can simply I hate you.
So the hatred between Mr. and Mrs. Han Chu is not that serious, at least it can be reconciled. Since it can be reconciled, it is reasonable to be together in the end. Judging from Chu Ci's last meeting with Han Yue before his death and Chu Ci's subtle temptations in the extra story, at least he fell in love with him in the end.

Character Analysis of Chu Ci
Chu Ci, the character in Huaishang's "Looking at the Bayonet with a Lantern", on the one hand, is very cruel and cold-blooded , contrary to morality; but on the other hand, you can't blame him, even Han Yue, whose relatives were killed by his beloved, can't do anything.
Imagine that you love someone so much that you care deeply about it, but he brutally hurts your loved ones behind his back, but you still love him helplessly, as if you were poisoned. Love him.
But Chu Ci is kind-hearted after all. Revenge cannot save him, and the dead cannot be traced. Killing has made him bear more weight. In the end, what he got was not the pleasure and relief after revenge, but a deep fear. He began to dare not be alone in a claustrophobic environment.
