"I, I saw a ghost chasing me from behind..." This is one of Bai Qi's few childhood memories. He thought he had forgotten it, but unexpectedly, he gradually returned to his nest as an adult. The old friends I'm looking for, the colleagues I travel with, and the roommates who have always been with me. All this makes the approaching night less scary. If the light has not appeared yet, I am willing to create a light for you. If the dark night has not dissipated, I am willing to break through this silent sky for you. This is a story of loving and being loved, protecting and being protected. Not just love, but also friendship, family ties, and bonds.
