Two strangers separated by time find each other through a crackling radio signal in Ditto, a 2022 South Korean romance that trades on longing more than spectacle.
What is Ditto about?
The setup is deceptively simple: a man and a woman, living in different eras, begin exchanging words over a shortwave radio, first out of curiosity and then out of something closer to need. Director Seo Eun-young lets the mismatch between their worlds do the emotional heavy lifting, using the radio itself as a stand-in for every relationship that survives on voice alone. Running 114 minutes, the film keeps its focus tight on the two leads and the growing weight of conversations neither can fully explain. K-Time carries the film with Farsi dub and Persian subtitle options.
About the cast
Yeo Jin-goo and Cho Yi-hyun anchor the two timelines at the center of the story, with Kim Hye-yoon, Na In-woo, Bae In-hyuk, Roh Jae-won, Nam Min-woo, and Lim Yu-bin rounding out the supporting cast. The split-era structure asks the leads to carry long stretches of screen time largely apart from each other, communicating through voice rather than shared scenes.
Context & significance
Ditto belongs to a recurring strand of Korean romance built on a communication gap between its leads — letters, time slips, radio waves — where the obstacle itself becomes the source of intimacy rather than an interruption to it. That structure has traveled well internationally because it turns distance into a narrative engine instead of a plot problem to be solved. South Korean dramas and films of this type have found a steady audience among diaspora viewers who favor character-driven stories over action-heavy alternatives, and Ditto's radio-era setting adds a texture that period romance fans in particular tend to respond to.
Watching Ditto on Ktime
Ditto is available on K-Time with a Farsi dub and Persian subtitles, letting viewers pick either format from the player controls. The page itself is free to read, and watching requires only a free account login. K-Time's Farsi-first design is built around exactly this kind of international romance, presenting Korean film and television in a Persian-language interface rather than requiring viewers to navigate an English-only platform.
