The rollout idea
The EP’s six songs each received an individual video across a daily sequence. Birthday Cake and Friendly Fire were the final two standalone releases.
What came next
A compilation joining all six videos was scheduled for September 16 at 6 p.m. Korea time, following the EP’s September 11 release.
The flip side
The two Allkpop pages document different stages of the same campaign and rely on the artist’s rollout information. They should not be counted as two independent confirmations or as separate album announcements.
Update note: Original source-read briefing adds specific context and evidentiary limits beyond the short feed summary.
