The change apparent from this description is an expansion of the scope of observation. The mystery now includes not only the scenes in plain sight but also the hidden side behind them. Detailed rules must be checked in the description for each episode. tvN program introduction and episode 1 preview

Spoiler-Free Episode 1 Synopsis

Episode 1 is structured around finding the fake among performances unfolding before the cast’s eyes. The theme of the official preview is “Don’t Believe It! SHOW!” The cast encounters locations that combine food and performances.

The preview features a performance using fire. It also introduces a café themed around famous paintings. A location featuring a taekwondo performance is another subject of the investigation.

What to Watch For

A key point to watch is the moment when first impressions conflict with additional clues. This viewing criterion is derived from the official introduction’s emphasis on the hidden side. The following points do not reveal the actual answer.

• Basis of the first judgment: Pay attention to what the cast sees and finds suspicious.
• Connecting the clues: See whether new information supports their existing judgments.
• Changes in reasoning: Watch how they interpret the same scene differently.

Comparing the Original Broadcast, Rebroadcasts, and Online Videos

tvN broadcasts and the official video list offer different content. The video page includes previews and videos containing portions of the broadcast. This list should not be interpreted as providing full episodes.

Being listed on TVING alone does not establish that the program is immediately available to play. The release time for the full episode also cannot be confirmed from that list. Viewing fees must be checked through the terms shown on the actual playback screen. Upcoming content on TVING

Why the Morning Rebroadcast Is Confused with the Episode Runtime

The 8:00 a.m. broadcast on September 14 is not the premiere. The program website marks this time slot as a rebroadcast. The premiere and rebroadcast information appear together on the same page.

The period from 8:00 a.m. to 9:35 a.m. is 95 minutes. This is the calculated length of the listed broadcast slot. It cannot be generalized as the video runtime of every episode.

How to Check Later Rebroadcasts and Channel Numbers

Later rebroadcasts can be checked on tvN’s official schedule. (Verified information: episode 1 rebroadcast on September 14, 2026, from 8:00 a.m.–9:35 a.m., 3:00 p.m.–4:35 p.m., and 11:55 p.m.–1:25 a.m. on September 15, 2026 · Source: tvn.cjenm.com · Verified on 2026-09-14) Check both the program title and episode number.

3. Check the episode number for Sixth Sense: B-Side and whether it is marked as an original broadcast or rebroadcast.
