In this episode, Bong-hwan begins to regain the original Queen So-yong’s memories. This creates a "deep essay" on the nature of the soul: if you possess someone else's memories, feelings, and biological instincts, do you remain yourself, or do you become them? The episode masterfully portrays the terror of losing one’s original identity to the overwhelming presence of the "host" body.

The core of Episode 6 revolves around the existential struggle of "The Queen Who Has No Self." While the series is often categorized as a romantic comedy, this specific episode delves into the profound psychological weight of living another person’s life.

The ending of the episode, featuring the long-awaited rain, symbolizes a momentary cleansing. For Bong-hwan, the rain represents a chance to return home (via the lake), but for the King, it represents a moment of genuine human connection with a woman he is beginning to realize is far more complex than a mere political ally.
