A new Korean drama called “Moon River” will premiere on October 31, 2025, and has released a new poster showing its main stars, Kang Tae Oh and Kim Se Jeong, sharing a sweet moment. The image captures the two actors holding hands and smiling warmly at each other in a sunlit forest, creating a romantic and exciting preview of their on-screen relationship.
The Story Behind “Moon River”
“Moon River” is a historical fantasy romance drama set in the Joseon era. The story follows a crown prince named Yi Kang, played by Kang Tae Oh, who has lost his ability to smile. His life changes dramatically when he crosses paths with a woman named Park Dal Yi, played by Kim Se Jeong, who has lost her memory. Through a mysterious event, their souls are swapped, forcing them to live each other’s lives.
The drama is written by Jo Seung-hee and directed by Lee Dong-hyun. It will air on MBC TV every Friday and Saturday at 9:50 p.m. KST.
A Closer Look at the Main Poster
The newly released main poster highlights a significant change in the relationship between the two main characters. In the poster, Park Dal Yi is seen wearing an elegant silk dress, a departure from her usual merchant clothing, looking bright and graceful. On the other hand, Yi Kang, who is known for his gruff and cold personality, is shown gazing at her with tender and affectionate eyes.
The two are holding hands in a forest bathed in soft sunlight. The subtle shift in the atmosphere between them suggests a budding romance that will be a central part of the story. This gentle image contrasts with other playful posters that have been released, which hint at the chaos their soul swap will cause.
Teaser Posters Hint at a Playful Dynamic
Earlier teaser posters for the drama showcased a more humorous side to the story. In one poster, a grumpy Crown Prince Yi Kang holds a tiny Park Dal Yi in his hand like a paper doll. Another poster shows the situation reversed, with Park Dal Yi dressed in the crown prince’s royal robes, flashing a mischievous smile as she holds a miniature Yi Kang.
A third special poster features an imaginative design where Yi Kang appears to be perched on top of Park Dal Yi’s traditional woven bamboo hat. The hat features an ink wash painting-style landscape, and their expressions—her bright, laughing eyes and his look of helplessness as he clutches the cotton decoration—create a playful and intriguing visual.
These posters are tagged with the phrase, “A chaotic, soul-swapping romance between complete opposites,” which perfectly sums up the unique premise of the show.
