Time

When life becomes a tradable currency This is a story about "time". But the "time" here is not the time passing on your desk - it is the visible, quantifiable, and tradable life energy itself. Red is the lowest, gold is noble, and the legendary white only exists in the bodies of the oldest living beings in the world. In this world, all order is based on the distribution of "time". An outer-ring boy, a needle without reading, fights against a system that controls everyone's lifespan.
