CORTIS Secret Space Seoul Guide: Dates, Reservations, Location Details, and Pop-Up Activities

CORTIS Secret Space Seoul is the Airbnb-hosted fan experience connected to CORTIS’ “REDRED” release and second EP [GREENGREEN]. The main public program is “POP-UP: Airbnb & CORTIS Seoul Hideout,” a free-reservation pop-up scheduled to run in Seoul from May 1 to May 7, 2026.¹

For readers looking for the practical details, this is best understood as a reservation-based pop-up rather than a general concert, release party, or walk-in fan event. The Seoul program also included smaller late-April experiences, but the May 1-7 pop-up is the broader public-facing portion designed to let more than 1,000 people experience the space.²

CORTIS Secret Space Seoul Key Facts

Airbnb introduced the Seoul secret space as a “Green vs. Red” experience built around “REDRED,” the title track connected with CORTIS’ second mini album [GREENGREEN].² In a short statement, CORTIS said it was meaningful to invite COER, the group’s fandom, into CORTIS’ Seoul secret space.²

The schedule has three separate parts. The April 28 member-facing experience has already passed. The April 29-30 overnight stay has also already passed. The part most relevant to general visitors is the May 1-7 pop-up, which is the wider access program for fans and visitors who want to see the CORTIS Secret Space in Seoul.²

Korea JoongAng Daily reported that Airbnb prepared the CORTIS Seoul Hideout in Seongdong District, Seoul, with a member-involved experience for up to 30 people, an overnight stay, and the May 1-7 pop-up for more than 1,000 visitors.³ Maeil Business Newspaper also described the April 28 event as a 30-person experience, the April 29 stay as a one-team lodging program, and the May 1-7 pop-up as the wider viewing opportunity.⁴

How Booking and Access Work

Reservations for “POP-UP: Airbnb & CORTIS Seoul Hideout” opened through Airbnb at noon on April 23, 2026, and were announced as free.¹ Because the event was presented as a secret space, the available source material does not treat it like a standard venue listing with a fully public address from the beginning. Instead, detailed on-site information was scheduled to be announced on April 30 through Airbnb Korea’s X account and China’s RedNote channel.¹

That means readers should separate confirmed information from assumptions. The confirmed details are the Airbnb reservation route, the free reservation opening time, the May 1-7 operation period, the location-announcement channels, and the fact that the public pop-up is planned for more than 1,000 participants. The source material does not provide walk-in rules, standby procedures, exact session times, age limits, cancellation terms, or refund rules.

The member appearance detail is also important. The broader Seoul program included a member-facing experience on April 28, but the May 1-7 public pop-up does not include CORTIS members appearing on site as part of the plan.² Visitors should therefore treat the public pop-up as an immersive fandom space tied to the release, not as a guaranteed artist appearance.

What Visitors Can Expect Inside the Pop-Up

The Seoul Hideout is organized around the contrast between red and green, matching the “REDRED” concept. Airbnb’s English announcement lists red and green concept zones, keycard and keycap collecting, UV clue finding, and mailroom bingo as parts of the pop-up experience.¹ AJU Press also reported interactive elements including a Red Room, Green Room, UV light crossword activity, card key and keycap collection, and mailroom bingo.⁵

Maeil Business Newspaper’s English coverage described the space as including red and green zones, a mailroom, a stay room, and a canvas wall, all reflecting the “REDRED” concept.⁴ These details point to a visit built around exploration and participation rather than passive display only.

There is also a visitor benefit connected to the campaign. AJU Press reported that pop-up visitors, along with Airbnb guests staying in Korea between April 23 and May 7, would have an opportunity to receive six unreleased “Square Pic” photos.⁵ The source material does not state that every visitor is guaranteed the photos, so the safest reading is that it is an opportunity connected to the event period.

The music context extends beyond the pop-up itself. BIGHIT MUSIC announced through Weverse that CORTIS’ “REDRED” release party was scheduled for April 20, 2026, at 8 p.m. at YES24 LIVE HALL in Seoul, and that the [GREENGREEN] release party was scheduled for May 4, 2026, at 8 p.m. at SFACTORY D.⁶ Those release-party dates help explain why the Airbnb Seoul Hideout is positioned around this specific CORTIS comeback period.
