Lee Dong Wook, Jung Yoo Mi, and Jeon So Nee Eye Netflix's Love Affair

Lee Dong Wook (이동욱), Jung Yoo Mi (정유미), and Jeon So Nee (전소니) are all in talks for Netflix's upcoming drama Love Affair, a psychological romance-thriller from director Mo Wan Il of The World of the Married. According to reports citing production company FNC Story and each actor's agency position, the series follows a married government worker whose life unravels after he meets another woman in Madrid. That logline is already sharp, but the bigger reason the project is drawing heat is the team behind it. Mo built his reputation on emotional implosion, not soft-focus melodrama, and Netflix gives him a larger stage than JTBC ever could. This is why the casting update matters beyond fan-service headlines. If these negotiations close, Love Affair immediately becomes one of the year's most volatile K-drama setups, not just another early-stage industry whisper.

A dangerous triangle split between Korea and Madrid

The setup is deceptively simple, but the emotional mechanics are designed for damage. According to FNC Story's story description as relayed in Korean coverage, Kim Ji Hoon is a government worker in his early 40s with a stable career and a happy marriage before meeting a woman in Madrid. The encounter triggers a romance that arrives, in the company's own phrasing, like lightning on a clear day and sends his once-stable life toward collapse. Lee Dong Wook has been offered Kim Ji Hoon, Jung Yoo Mi is considering his wife Lee Sun Hee, and Jeon So Nee is reviewing Gong Hoo Kyung, the architect whose path crosses his in Spain. The Madrid setting matters too. It gives the affair narrative a genuine displacement element instead of trapping the whole concept inside familiar domestic-drama geography.

Mo Wan Il is returning to territory he understands better than most

Mo Wan Il's name is carrying as much weight here as the cast. The World of the Married peaked at 28.4 percent on JTBC in 2020 and was widely treated as a cultural event, not just a ratings success. According to Korean media reports on the new project, Love Affair will again deal with infidelity, but this time with more overt thriller pressure built into the frame. That distinction matters because Mo is not simply revisiting old material. He is revisiting it with Netflix scale, a cross-border setting, and a cast better known for charm, melancholy, and restraint than outright moral combustion. If you have been tracking how streamers are reshaping Korean drama packaging, our look at how Korean broadcasters are adapting to Netflix's pace sits naturally beside this story.

The casting works because it pushes the leads off their easiest settings

The most interesting part of the package is how each role cuts against familiar audience expectations. Lee Dong Wook is best known globally for series such as Guardian: The Lonely and Great God, Bad and Crazy, and Tale of the Nine Tailed, where charisma and control are part of the appeal. Playing Kim Ji Hoon asks for something messier: a man who detonates the life he built. Jeon So Nee, meanwhile, has often been cast with cooler restraint than overt disruption, which makes Gong Hoo Kyung a more combustible fit. Jung Yoo Mi's position may be the most painful of all because Lee Sun Hee is not a symbolic spouse. She is the person left to absorb the fallout. That distribution of pain is why the casting landed fast in drama-watcher circles.

Netflix gives the premise a bigger runway, but negotiations are still ongoing

As reported by the outlets carrying the casting update, FNC Story is producing Love Affair for Netflix global distribution, with filming expected to begin in the first half of 2026. That scale changes the stakes. The World of the Married was already huge inside Korea, but Netflix makes this kind of morally volatile material immediately legible to an international audience that has grown comfortable with darker K-drama relationship stories. At the same time, none of the three leads has formally locked the deal yet, so the story is still a casting-in-talks report, not a production start notice. Even with that caveat, the package is strong enough to matter now. If the agencies say yes, Love Affair moves straight into the serious watchlist tier.
