Yu Ange, the daughter of a military family, was killed through the joint schemes of Song Jiner, a woman who had transmigrated into this world, and her fiancé, Cen Jiashu. Only after her country fell and her family was destroyed did she discover that she was merely a cannon-fodder character in a book. Reborn, she disguises herself as a man and takes her elder brother's place in the capital, stepping over the corpses of her enemies as she advances toward the imperial court. She vows to tear apart the absurd ending of a romance said to be worth a kingdom, while he seeks to reclaim everything that belongs to him amid deadly power struggles over the throne. When every debt has finally been settled, she plants a foot on the imperial throne. This seat is mine.
