“Sixth Sense: Bside” Sets September Premiere With BIBI Joining New Cast

tvN’s “Sixth Sense” is returning with a new season titled “Sixth Sense: Bside”, bringing together Yu Jae Seok, Song Eun Yi, Ko Kyung Pyo, and BIBI. The program will premiere on September 13 at 7:50 p.m. KST.

The first teaser was released on August 14, introducing a refreshed lineup and a familiar challenge. The cast will visit viral hotspots and trendy destinations, then use observation, wit, and teamwork to determine which location or concept is the one fake hidden among the real examples.

Yu Jae Seok and Ko Kyung Pyo return from the show’s previous lineup. Song Eun Yi is making a comeback to the program, while BIBI joins “Sixth Sense” as a cast member for the first time.

A familiar mystery format in new locations

The central structure remains built around deception. Rather than asking the cast to solve a conventional crime or puzzle, each episode places them among places designed to feel current and convincing. Their task is to notice which details do not belong.

Viral hotspots and trendy destinations provide a natural setting for the format because unfamiliar venues can be difficult to judge at first glance. A real location may appear exaggerated, while a fabricated one can be made plausible. That uncertainty gives the cast room to test theories and challenge one another’s instincts.

The subtitle “Bside” distinguishes the season from earlier versions while preserving the “Sixth Sense” identity. The announcement does not explain whether the subtitle signals additional rule changes, so the confirmed format remains the search for one fake among real locations.

No guest list, episode count, or complete schedule beyond the premiere time was announced with the teaser. The initial reveal therefore focuses on the four main cast members and the destinations they will investigate together.

Returning members meet a refreshed lineup

Yu Jae Seok returns as a familiar anchor for the program. His presence provides continuity with earlier seasons and places an experienced variety host at the center of a cast that combines previous participants, a returning face, and a newcomer.

Ko Kyung Pyo also returns for “Bside.” His continued participation gives the new season another direct link to the previous lineup and means that two members already understand the show’s unusual balance of skepticism, improvisation, and group decision-making.

Song Eun Yi’s comeback adds another experienced entertainer to the group. The announcement frames her as returning to the program rather than joining it for the first time, making her part of the season’s bridge between the established format and the new configuration.

BIBI is the only first-time “Sixth Sense” cast member in the announced quartet. Her addition introduces a new perspective to a game that depends heavily on personal reactions. Because the cast must compare suspicions and reach conclusions, a newcomer’s instincts can change the way the group evaluates each clue.

What the first announcement confirms

The core facts are now set: “Sixth Sense: Bside” will air on tvN, premiere September 13 at 7:50 p.m. KST, and feature Yu Jae Seok, Song Eun Yi, Ko Kyung Pyo, and BIBI. The cast will explore popular destinations and identify a fake hidden among genuine examples.

The teaser confirms the return of the franchise but leaves many episode-level details for later. Specific locations, fabricated setups, guest appearances, and the way the cast divides its investigations have not yet been revealed.

That limited preview keeps attention on the new chemistry. Two returning members offer continuity, Song Eun Yi brings comeback experience, and BIBI enters the format for the first time. When the season begins, their ability to read both the locations and one another will be central to whether they can separate a carefully built illusion from reality.
