The cannon-fodder fiancée in the novel "The Overlord" is dressed as a beast in modern society. In order to avoid being resented and retaliated by the male protagonist and thrown into a mental hospital, she desperately stayed away from the male protagonist and matched him with the original female protagonist. As a result, the male protagonist imagined all her "escape behaviors" as "affectionate temptations" and got deeper and deeper. Finally, when the male protagonist conquered himself to the point of being hopeless, the female protagonist discovered that the male protagonist had long known that she was not the original protagonist and had been accompanying her in this "escape drama".
