- The essence of political scheming: The heart of a power struggle is not who wins or loses, but "who defines the rules." The protagonist tries to use his enemy's rules to take revenge, only to discover that he has long since become a sacrifice to a new set of rules.

Yet, as they clash, they gradually become each other's one and only weakness.
