Yan Sen, 24, has always felt that his life would be like the dense trees in front of the house in the compound, quiet, dull and depressing.
Until he met Qi Zhaoyang, like bright sunshine, shining into his life. But the depression around him is eroding the beauty bit by bit

In the end, he couldn't even tell what was light and what was darkness.
Concept: Behind the light is darkness, and above the darkness is light.
