They are each other's weakness and also each other's sharpest knife.
Shen Li is responsible for playing chess, and Shen Yue is responsible for closing the net.
One has been planning in the dark for ten years, and the other is smiling like a flower in the open.
No one in this world knows what "living" is better than them -
That is the way to climb out of the mud, break bones, and walk into the sunshine.
They've done bad things and they've had good dreams.
They have killed people and saved people.
They are each other's abyss and each other's only light.
Twin flowers, if one dies, the other will not survive alone.
But if both have to live to the end - don't blame them, they are smarter than the villain.
