Han So-hee and Nam Joo-hyuk to Headline New Romance Drama "Heartbeat"

Han So-hee and Nam Joo-hyuk are set to headline the upcoming fantasy romance drama Heartbeat (working title), marking the first time the two stars will appear together as lead actors in a drama.
The project has already attracted attention thanks to its high-profile pairing and its creative team. The series will be written by Lee Si-eun, the screenwriter behind hit dramas True Beauty and Lovely Runner, while Bon Factory, the production company behind Lovely Runner, is also involved in the project.
Han So-hee and Nam Joo-hyuk's First Drama Together
Heartbeat will bring Han So-hee and Nam Joo-hyuk together for the first time as drama leads.
Nam Joo-hyuk was confirmed as the male lead earlier in the casting process, while Han So-hee's agency 9ato Entertainment initially stated that she had received an offer and was positively considering the role. Subsequent reports have since listed the two actors as the leads of the upcoming project.
The pairing has generated considerable interest among fans, particularly because the two actors have previously appeared together at fashion events as Dior ambassadors. Their upcoming collaboration will now move that chemistry from the fashion world to the screen.
What Is Heartbeat About?
Heartbeat is described as a fantasy romance centered on a woman who has the ability to see the past and a man who is hiding his own past.
The story begins when the woman encounters a man who looks exactly like her deceased first love. Their unexpected meeting sets off a series of events that brings the two characters together and explores the idea of an "immortal first love."
Han So-hee is set to play Hong Sa-rang, the female lead who can see the past, while Nam Joo-hyuk will portray Cha Shin-jo, a man who bears an uncanny resemblance to her late first love and hides his past.
From the Writer of Lovely Runner
One of the biggest reasons for the anticipation surrounding Heartbeat is its screenwriter.
Lee Si-eun, who previously wrote True Beauty and Lovely Runner, is behind the screenplay. Her involvement gives the upcoming romance an additional connection to some of the most recognizable Korean romance dramas of recent years.
The drama is being produced by Bon Factory, the company behind Lovely Runner, further strengthening the connection between the two projects.
When Will Heartbeat Begin Filming?
Production is currently scheduled to begin in late 2026.
An official premiere date and broadcasting or streaming platform have not yet been announced, so further details about the release schedule are still expected.
