In the cracks of the world, there is a mysterious organization called the "Rule Bureau". They maintain all the rules that humans rely on for survival - from gravity and time to laws and contracts. But what you don't know is that the rules bureau is not guarding the rules, but manipulating them.
Shen Yezhou, the most wanted criminal in the Rules Bureau, numbered "S". He has the ability to "rule erosion" - any rules he touches will gradually become ineffective. He is cynical and paranoid, and likes to use the rules as scratch paper to revise. No one knows his origins because he is not human himself - he is an out-of-control rule born in the "Great Collapse" event ten years ago.
Lu Yanzhou, executor No. 001 Of the Rules Bureau, is the only son of the director. He has the ability of "rule solidification" - he can turn temporary rules into permanent rules at the cost of consuming his own lifespan. He is cold-faced, ascetic, extremely self-disciplined, and never says an unnecessary word. There are fragments of the "original rules" sealed in his body, which is a second personality that may swallow him at any time.
Ten years ago, an experiment trying to rewrite the "Law of Causality" caused the Great Collapse, and the Rules Bureau covered up the truth. Ten years later, Shen Yezhou sneaked into the Rules Bureau to steal confidential files, and met Lu Yanzhou who was ordered to capture him.
When they met for the first time, the two found that each other's abilities restrained each other - no one could win.
In the second encounter, a third-party force suddenly attacked. They were forced to face the enemy back to back, and their cooperation unexpectedly reached a tacit understanding.
When we met for the third time, Shen Yezhou said, "I won't show mercy next time." Lu Yanzhou said, "You don't have a next time."
But none of them thought that the rules bureau itself was the biggest enemy. As the truth emerges bit by bit, they change from enemies to allies, from allies to the only people who can be trusted, from trust to... No one can live without anyone.
This is a showdown between rules and anti-rules, as well as an emotional long-distance race of even rivalry and mutual redemption.
When rules become shackles, do you choose to obey or break them? When that person becomes your exception, do you choose to escape or embrace it?
Intention: "When the rules become shackles, we choose to rewrite them - for ourselves, and for the sake of the person who doesn't want to lose."
