In a future where time becomes currency, your life is just a number in the system.
The duty of top recycler Lin Xiao is to arrest those "stranded people" who refuse to hand over their remaining time and maintain the order of the world. Until she met the girl - her time meter showed a number that could never exist: a negative number.
As a result, the city's time order collapsed, and the lost friends emerged in the countercurrent. Lin Xiao was forced to be involved in a huge conspiracy. She discovered that the core of the cold and precise system that kept the world running turned out to be a big lie.
When memories can be tampered with and fate can be reclaimed, will she choose to continue to be the sharp blade of the system, or will she become the only edge that pierces lies?
Is time really irreversible?
