There were many examples of the male protagonist's name being Nangong Yu and the female protagonist's name being Han Yin 'er, but not all time-travel novels had such a setting. In some novels, the name of the male protagonist may be the name of another character such as a hero, villain or mysterious figure, while the name of the female protagonist may be the name of another female character such as a queen, princess or wonderful woman. Some novels would combine the names of the male and female protagonists with a certain myth or legend to create a unique name combination. Therefore, the names of the male and female leads would depend on the plot and setting of the novel.
