Cheng Munan and Li Yeluo are the doomsday twins who have marked each other's flesh and blood.
He gave him the stability of a rock and gave him his remaining tenderness.
With love as a cocoon, Li Yeluo personally pushed Cheng Munan towards the beam of light - a dead end path that he mistakenly thought was the way to survive.
Cocoon becomes rope.
When Cheng Munan burned his body to preserve his dignity at the end of his misjudgment, all that was left in Li Yeluo's world was the noose with love as its thread, tightening tighter and tighter until both his ideals and his broken body were severed.
Not all fiery cocoons can hatch light. Sometimes, it is just a noose that tightens the twin souls and leads to the abyss.
Purpose: When disaster strikes, human beings always move forward cruelly
