A story about love and hate entanglements in the fictional background of the Republic of China (high technology, solidified classes, and a future empire set to resemble the aristocracy of the Republic of China). The core is the "identity counterattack" and "rescue sadomasochism" between the high-level sick and weak daughter and the low-level super-powerful god of war. The heroine thought she was using power and tactics to take advantage of a useless person, but in fact the imperial order she relied on for survival was about to collapse, and the only person she could trust was the "fugitive" she bought. The whole book revolves around "fake use of true love" and "two-way redemption under class barriers".
