The Plot

Lee Gon, the modern-day emperor of the Kingdom of Corea, attempts to cross the barrier into an alternate world where the Republic of Korea exists instead of the monarchy. In this world, he meets investigator Jeong Tae-eul (played by Kim Go-eun), a woman he recognizes from an identity card connected to a traumatic event from his past, the assassination of his father. As Lee Gon travels between these two parallel worlds, his treacherous half-uncle, Lee Lim (played by Lee Jung-jin), the man responsible for the murder of King Lee Ho (Lee Gon’s father), remains in hiding and is gathering forces to challenge the throne.
The Characters
Lee Gon / Lee Ji-hun (played by Lee Min-ho)

Lee Gon is the third emperor of the Kingdom of Corea, a man of intellect, athleticism, and deep emotional restraint. A gifted mathematician, equestrian, and rower, he is rarely seen without his majestic white horse, Maximus. Behind his regal demeanor lies a guarded soul, one that is uncomfortable with physical contact and slow to trust. At the age of eight, his world was shattered when he witnessed the assassination of his father, King Lee Ho, at the hands of his half-uncle, Lee Lim. In a twist of fate, a mysterious figure bearing Jeong Tae-eul’s ID saved him from death that night, an image that haunts and guides him as he navigates between parallel worlds.
In the alternate world, his counterpart, Lee Ji-hun, was a young boy who tragically lost his life when Lee Lim crossed over after murdering the king.
Jeong Tae-eul / Luna (played by Kim Go-eun)

Jeong Tae-eul is a determined and tough investigator with the Violent Crimes Squad of the Republic of Korea’s National Police Agency. Strong-willed and fiercely grounded, she grew up inspired by crime dramas and chose to dedicate her life to justice.
Her doppelgänger in the Kingdom of Corea is Luna, a criminal born in the shadows of Busan’s slums, with no family, identity, or legal existence. Luna’s life spiraled into crime, marked by arrests for theft, assault, and forgery. Now terminally ill with organ failure caused by cancer, Luna’s days are numbered, adding urgency and complexity to her path.
Jo Yeong / Jo Eun-sup (played by Woo Do-hwan)

Jo Yeong is the stoic and formidable captain of the Royal Guard in the Kingdom of Corea and Lee Gon’s closest friend since childhood. At the young emperor’s coronation, Jo Yeong swore unwavering loyalty to both the throne and the man who occupies it, regarding Lee Gon as both his king and his law.
In the Republic of Korea, his cheerful and carefree counterpart, Jo Eun-sup, is currently serving in the military as part of the National Police Agency. Light-hearted and playful, Eun-sup is devoted to his family, helping raise his mischievous twin siblings, Eun-bi and Kka-bi, and quietly harbors feelings for his childhood friend, Myeong Na-ri.
Kang Shin-jae / Kang Hyeon-min (played by Kim Kyung-nam)

Detective Kang Shin-jae is another member of the Violent Crimes Squad in the Republic of Korea. His early life seemed stable until it crumbled under the weight of his mother’s gambling addiction and his father’s imprisonment for embezzlement. Emotionally scarred yet quietly loyal, he has harbored unspoken feelings for Jeong Tae-eul since their high school days.
In the Kingdom of Corea, his counterpart, Kang Hyeon-min, leads a very different life, shaped by the altered course of their shared fate.
Koo Seo-ryeong / Koo Eun-ah (played by Jung Eun-chae)
Koo Seo-ryeong is the Kingdom of Corea’s youngest and first female prime minister, brilliant, poised, and ruthlessly ambitious. Despite a humble upbringing with a hardworking mother and an alcoholic father, she climbed the political ladder, first as a diplomat, then as an announcer, and finally into the prime minister’s seat. Her marriage to the chairman of KU Group was short-lived, ending in divorce and alimony, a move that only fueled her thirst for power. Now, her eyes are set on the throne itself.
Her counterpart in the Republic of Korea, Koo Eun-ah, mirrors her in form but lives an entirely separate life, grounded in a different reality.
Lee Lim / Lee Seong-jae (played by Lee Jung-jin)

Lee Lim, also known as Prince Imperial Geum, is the illegitimate half-brother of King Lee Ho and the man behind the royal assassination. Obsessed with obtaining the legendary Manpasikjeok, a mythical flute believed to grant immortality, Lee Lim kills the king and steals the artifact. Before young Lee Gon intervenes with the Four Tiger Sword and shatters the flute in two, Lee Lim escapes to the parallel universe, murdering his alternate self there. Now, in hiding, he works to reclaim the flute’s second half from Lee Gon, seeking ultimate control over time and space itself.
