As hallmark of Korean mythology as well as that of other cultures in the region, this symbol traditionally suggests that the universe binds two souls together; they are destined to meet and affect each other’s lives. In the context of the novel, the Red String initially binds Mina to the Sea God, suggesting a destiny that is beyond her control and steeped in sacrifice and duty. However, as Mina’s journey progresses, the Red String evolves beyond its traditional interpretation. When it shifts to connect her to Shin, this event challenges the notion of an unalterable destiny, for it symbolizes the fluidity of fate and the potential for individuals to redefine their paths. Thus, the Red String encapsulates the novel’s exploration of The Interplay of Destiny and Free Will, suggesting that while certain connections may be predestined, personal choice powerfully influences how such connections will manifest.

The Red String thus becomes a visual and thematic thread that runs through the narrative, representing the tension between the inevitability of certain life events and the power of human agency to influence these events. Oh uses this symbol to implicitly raise questions about the nature of destiny, and Mina must ultimately learn whether she is to follow a predetermined path, or whether she is expected to navigate and interpret that path for herself as she grows and changes throughout her experiences.
