Seongri, Jang Han-byul and Haru Join Jeon Hyun-moo Plan 4 for Sacheon Episode

Seongri, Jang Han-byul, and Haru are heading to Sacheon for MBN’s Jeon Hyun-moo Plan 4, adding a music-focused guest lineup to the food and travel variety show’s second episode.

According to a July 12 report from The Public and MBN’s own program preview page, the three artists will appear with Jeon Hyun-moo in an episode centered on Sacheon, a coastal city in South Gyeongsang Province. The broadcast is scheduled for Friday, July 17, at 9:10 p.m. KST, matching the show’s regular Friday-night slot.

The appearance brings together three performers who have recently been spotlighted through Unknown Legend, with the report describing them as the program’s “TOP3.” Rather than presenting them only as studio guests, the Sacheon episode is expected to place the artists inside the show’s familiar travel format, built around local food, regional scenery, and informal conversation.

A Music Lineup Meets a Regional Food Trip

Seongri is known as a former boy group member who has continued building his career through solo releases and original soundtrack work. The Public noted his reputation for emotional vocals, a point that fits the episode’s expected blend of talk, performance, and personal storytelling.

Jang Han-byul enters the episode with a different route to public recognition. He first debuted as the main vocalist of the band LEDApple and later expanded his profile overseas, including winning Malaysia’s audition program Big Stage. His appearance follows additional activity around fan events and broadcast stages, giving the Sacheon trip a timely promotional angle without making it feel like a standard music-show stop.

Haru, described as a singer-songwriter with a distinctive vocal tone and stage style, represents the independent-leaning side of the lineup. The report said Haru has been widening public recognition through Unknown Legend, which makes the MBN appearance another chance to introduce that identity to a wider entertainment audience.

The episode’s setting matters because Jeon Hyun-moo Plan 4 is not simply a guest interview show. The program’s appeal is rooted in movement: traveling through a city, eating local dishes, reacting to places in real time, and letting guest chemistry develop outside a formal studio environment. Sacheon’s mix of coastal scenery and regional cuisine gives the production a clear backdrop for both casual banter and performance moments.

Why the Guest Casting Fits the Show

The casting also reflects a broader trend in Korean variety programming, where singers are increasingly introduced through lifestyle, food, and travel formats rather than only through comeback stages. For artists trying to move from niche recognition to general-audience familiarity, a travel episode can show personality, humor, taste, and musical ability in one package.

For Seongri, Jang Han-byul, and Haru, the Sacheon episode offers a way to connect recent stage momentum with a more relaxed public image. The Public reported that the three have recently appeared on various broadcast stages, including KBS’s Open Concert, suggesting that their MBN outing is part of a wider run of public-facing activity.

The episode is also positioned to highlight local culture. The source report said the artists will enjoy Sacheon’s food and atmosphere while presenting various performances. That combination can be useful for both sides of the broadcast: the guests receive a personable showcase, while the city becomes more than a backdrop through food, travel, and music-led segments.

Viewers should not expect a traditional concert-style program. Based on MBN’s preview framing and the show’s format, the likely draw is the interaction between Jeon Hyun-moo’s variety pacing and three artists with different career stories: a former idol vocalist, a band-born singer with overseas recognition, and an indie-rooted singer-songwriter. If the episode balances those backgrounds with Sacheon’s local color, it could give the “Unknown Legend TOP3” a useful next step in front of a broader audience.

The new episode of Jeon Hyun-moo Plan 4 is set to air on July 17 at 9:10 p.m. KST on MBN.
