Joy Returns to K-Drama After 4 Years and Her Co-Star’s Botched “Nude Bath Scene” Is Already Stealing the Show

At the press conference for TVING’s “One-of-a-Kind Romance,” Red Velvet‘s Joy and rising actor Kim Hyun-jin turned an awkward body-prep confession into the funniest moment of the day and a preview of the chemistry driving their new mutual-fandom rom-com.

Sometimes the best way to sell a romantic comedy isn’t a trailer it’s watching the two leads accidentally roast each other in front of a room full of reporters. That’s exactly what happened on November 9 at the Seoul press conference for One-of-a-Kind Romance, when actor Kim Hyun-jin admitted he’d dieted and trained hard to physically transform for his role as a top star only to have the entire effort reportedly vanish under studio lighting because, as his co-star diplomatically put it, his skin is simply “too fair and flawless.”

It’s a small, funny exchange. But it’s also a surprisingly fitting entry point into a show that’s fundamentally about image versus reality what fans see of their idols, and what’s actually underneath.

A Four-Year Wait, Finally Over

For Red Velvet’s Joy (Park Soo-young), One-of-a-Kind Romance marks a genuine milestone: her first drama role in four years. That’s a significant gap for an idol-actor who built real credibility in the genre, and her return comes with specific intention she’s playing against type as Gong Yu-il, an ordinary, perpetually upbeat job seeker who juggles part-time work and employment prep while trying not to lose her optimism despite setbacks in both career and love. When Yu-il accidentally becomes the manager for one of the country’s biggest stars, her orderly, struggling-but-hopeful life collides head-on with his gilded, guarded one.

That star is Tak Mu-i, played by Kim Hyun-jin, a former LOONA and LOOSSEMBLE member turned actor who has been steadily building a drama résumé since his 2021 roles. Mu-i is written as a performer who projects effortless charisma on-screen while privately carrying the trauma of a past stalking incident a premise that gives the show’s central “mutual fandom romance” an unexpectedly layered emotional foundation. Both leads, in other words, are hiding something behind a persona: Yu-il behind relentless positivity, Mu-i behind polished stardom.

The Series That’s Been Years in the Making

One-of-a-Kind Romance is adapted from a Naver webtoon of the same name by creator Dooboo, following the increasingly reliable K-drama pipeline of turning proven webtoon romances into live-action series with built-in fan bases. The drama was first announced for a second-half 2026 release, and its path to screen has been closely tracked by international outlets well before its premiere a sign of how much international appetite there now is for Korean webtoon adaptations, particularly ones pairing an idol-actor with a known on-screen talent.

The series premiered on TVING in Korea on November 9 at 6 PM KST, with international distribution through Viu across parts of Asia, the Middle East, and Africa, and ABEMA in Japan a release footprint that underscores how much of the K-drama economy now runs on simultaneous multi-platform rollout rather than a slow international licensing trickle. New episodes drop in pairs every Monday, building toward a total of 12 episodes.

The Edited Scene Everyone Now Wants to See

Back at the press conference, director Kim Jin-young supplied the story’s best behind-the-scenes anecdote: Kim Hyun-jin’s character originally had a full nude bathing scene, shot with lighting the director says he second-guessed on set only to later learn no special lighting had been used at all. “I asked why the lighting was so intense,” he reportedly said, “but apparently they hadn’t done anything differently.” The scene, in the end, didn’t make the final cut a reveal that drew audible disappointment from the hosting MC and a round of laughs from the cast, including Kim Hyun-jin himself, who admitted he was only finding out about the edit in that moment.

It’s the kind of unscripted press-conference moment that tends to outlive the formal talking points, and it already has: co-star Shin Hyun-soo, who plays alongside the leads, added his own compliment to the pile, noting that Kim Hyun-jin’s height and genuine on-screen charisma made him feel, in the moment, like he really was standing across from a bona fide top star blurring the line between actor and character in exactly the way the show’s premise needs it to.

Why the Chemistry Matters More Than the Punchline

Light-hearted press conference banter aside, One-of-a-Kind Romance is making a specific bet: that audiences are hungry for a rom-com built on mutual vulnerability rather than one-sided rescue. Yu-il isn’t a passive fan swept up by fame she’s an underdog navigating her own stalled career, and Mu-i isn’t an untouchable celebrity he’s someone quietly working through real trauma behind the image. That’s a more textured premise than the “ordinary girl meets untouchable star” formula typically allows, and the easy rapport Joy and Kim Hyun-jin displayed on stage teasing, defending, and riffing off each other within seconds suggests their on-screen dynamic may carry that nuance convincingly.

Four years is a long time to stay away from a genre you’re good at. If the chemistry on display at Monday’s press conference is any indication, Joy’s return and Kim Hyun-jin’s star turn might be worth the wait.
