Chun Woo-hee and Kang So-ra are reuniting as travel partners on ENA and TEO’s Earth Marble World Tour 4. The new season premieres on October 17 at 7:50 p.m., with Chun, Kang, Kai, Park Myung-soo and Sehun revealed as partners for Pani Bottle, KwakTube and Wonji.

The show keeps its core setup: travel creators Pani Bottle, KwakTube and Wonji take part in a world-travel board-game format designed by producer Kim Tae-ho. Season 4 adds the Earth Marble Travel Film Festival concept, pairing the creators with new partners for fresh travel combinations.

Chun and Kang’s appearance connects back to the 2011 film Sunny, where they worked together. They later also appeared in Waiting for Rain. On this program, Chun joins as a traveler, while Kang participates as a planner-type traveler who still has to follow destinations decided by dice results.

Kai and Sehun are also part of the partner lineup, joining the travel-variety format away from the stage. Park Myung-soo joins as another partner, while Kyuhyun comes in as a new MC alongside Noh Hong-chul after Joo Woo-jae’s exit. Previous seasons recorded peak nationwide ratings of 1.5% in 2023, 2.3% in 2024 and 1.9% in 2025.
