A flame burns within everyone, the spark of will that keeps a person going. Those whose inner flame is about to die show no signs of illness that medicine can detect, yet one ordinary morning, they silently "go out." Chen Yan, owner of a repair shop in the old town, is one of the very few "Keepers of the Lamp" who can see these flames and pass some of his own fire to others. He can enter the body of someone whose flame is fading and live through the hardest part of their life in their place, helping them find a reason to keep living. The cost is that his own flame grows weaker and he grows colder, while the people he saves will never remember him.
He thought he was atoning for his sins and saving people. That is, until the truth behind the great fire three years ago began to unravel, layer by layer...
One lamp breaks the darkness, and its light shines for ten thousand years. There are no gods with superpowers in this world, only ordinary people willing to be one another's light.
