The four major families in Lincheng, Jiang, Shen, and Lin, stand side by side. Jiang Zhiyao, the daughter of the Jiang family, and Shen Zhixia, the daughter of the Shen family, have been best friends since childhood. Together with Lin Yanzhou, Shen Yanci, and Lin Shuyue, they have been an inseparable six since childhood, and have been in the same class from kindergarten to high school. Jiang Zhiyao seems to be living under the aura of the Jiang family. All her parents' favor goes to her younger brother, and only his younger brother truly protects her. Lin Yanzhou is her childhood sweetheart, always providing warmth when she is sad. As the elder brother of Shen Zhixia, Shen Yanci and Lin Yanzhou are life-long brothers. The five of them are bound to each other. In the hustle and bustle of Lin City, there is hidden their youth time, and there are also the subtle waves of family and worries.
"We once regarded each other as the only light, but Lincheng is so big that once the light is gone, it will never be found again."
Concept: "Teenagers bound by family and destiny regard each other as the only source of light; but when the halo is shattered into ashes, they discover that light can also burn people, and the most painful thing in the rest of their lives is not loss, but having to push each other back into the darkness with their own hands even though they clearly love each other."
