Zhang Wuji
Although Zhou Zhiruo is in love with Zhang Wuji, she has no choice but to turn against him because she is bound by an oath she made to her martial arts master, Abbess Miejue of the Emei Sect, who hates anyone related to the Ming Cult. Before her death, Miejue devises a vicious scheme for Zhou Zhiruo to seize the Dragon-Slaying Saber and Heaven-Reliant Sword by exploiting Zhang Wuji's love for her apprentice. Zhou Zhiruo secretly carries out this plan and attempts to push the blame to Zhao Min. Later, she turns vicious after Zhang Wuji publicly embarrasses her by abandoning her for Zhao Min just as she and Zhang Wuji are about to be married.
