Its core premise follows Lee Rin, a rebellious prince heir who becomes a night watchman battling ghosts and supernatural threats alongside Do-ha, a woman with nature-communicating powers from Mt. Baekdu, and supporting characters like Kang Moo-seok.

The storytelling centers on palace intrigue, romance, action, and ghost-hunting without any modern social justice framing, identity politics, or critiques of traditional norms. This traditional Joseon-era fantasy plot with supernatural elements contains no contemporary progressive themes or messaging, allowing the narrative to focus purely on entertainment through its blend of historical setting and ghostly encounters. The all-Korean cast fills period-appropriate roles with no race or gender swaps or forced diversity, preserving the cultural and historical authenticity of the story. Produced in 2014, well before activist media trends took hold, the series shows no evidence of creator statements or reception signals tied to ideology, reinforcing its commitment to straightforward storytelling over any ideological agenda.
