"Moon River" is an enchanting fantasy romance set in Joseon-era Korea, blending soul-swapping chaos, palace intrigue, and heartfelt redemption. Directed by Lee Dong-hyeon, this MBC drama promises a whirlwind of humor, heartbreak, and unexpected love between unlikely souls.

Overview

"Moon River" (Korean: "이강에는 달이 흐른다," also known as "The Moon Flows Over the River") is a 2025 South Korean historical fantasy romance drama directed by Lee Dong-hyeon, written by Jo Seung-Hee. Produced for MBC, the series airs every Friday and Saturday at 21:50 starting October 31, 2025, until December 13, 2025. It explores themes of lost happiness, memory, revenge, and second chances through a mystical body-swap narrative.

Plot Synopsis

In the turbulent Joseon Dynasty, Crown Prince Yi Kang, a regent burdened by his father's incapacity, lives a facade of reckless luxury while harboring a seething desire for revenge after the tragic loss of his beloved crown princess. Consumed by grief and palace power struggles, Yi Kang's meticulously planned retribution begins to unfold.

Enter Park Dal Yi, a quick-witted, amnesiac peddler who roams the markets with her sharp tongue, charming dialect, and uncanny resemblance to the late princess.

After a fateful encounter, the two inexplicably swap souls overnight, thrusting Yi Kang into Dal Yi's impoverished, chaotic world of haggling merchants and survival schemes, while Dal Yi awakens in the opulent yet treacherous palace, navigating royal duties and hidden enemies.

As they grapple with unfamiliar bodies, fragmented memories, and clashing personalities – his brooding intensity versus her fiery resilience – they unravel mysteries of the past, forge an unlikely alliance, and rediscover joy amid the soul-swapping mayhem.

The story weaves revenge plots, forbidden romance, and whimsical disguises into a tale of healing and fate.
