In folklore, the theme of duality is typically represented in relationships through the dynamics of opposites, such as light and dark, good and evil, or harmony and chaos. These dualities often manifest in myths where characters embody contrasting traits or face moral dilemmas, showcasing the balance inherent in life. Relationships highlighting duality emphasize that opposites can coexist and complement one another, reflecting the complexity of human emotions and the multifaceted nature of existence.
