The 'Scenario' teaser reached us from two directions at once. ONEWE posted the 41-second clip on their own YouTube channel at 22:00 KST on August 14, and 1theK posted the same clip at that same minute, so whichever channel we happen to follow, nobody had to wait for the other one.
The rollout started a day earlier. ONEWE posted a highlight lyrics book video at 22:00 KST on August 13, running 4 minutes and 59 seconds, and its description is where the release details sit: the band's third full album, '面 : Unknown Atlas', with a track list of 17 songs. 'Scenario' is listed first there, and it is the song this teaser is for.
Here is where the counters stand at the time of writing. The teaser on ONEWE's own channel has 18,993 views, 1,113 likes and 61 comments. The same 41-second clip on 1theK has 1,948 views, 180 likes and 8 comments. The highlight lyrics book from the day before has 13,076 views, 736 likes and 56 comments.
If you want to follow this from the source, the teaser description carries tags for the album and the song plus a release tag reading 20260819, and it links out to the band's own website and accounts. The 1theK description states the same date in plain form, listing the artist as ONEWE, the title as Scenario and the release as 2026.08.19.
