“Aerotherapy” opens oftheblue’s musical introduction; the official debut is scheduled for 2027.
A first single before the official debut
JYP Entertainment introduced its new boy group oftheblue with the predebut single “Aerotherapy” (풍선인간) on November 11, 2026. The song arrived at 6 p.m. KST, or 11 a.m. in Romania. The group’s official debut is scheduled for 2027, making the single an early musical introduction within a separate stage of its launch.
A blind performance video preceded the release at midnight KST on November 11. Running approximately one minute and 45 seconds, it partly conceals the members’ faces while moving between urban and natural settings. This initial presentation foregrounds movement and the project’s atmosphere ahead of a full introduction of the group’s identity.
Members contribute to the music
According to JYP’s announcement, reported by NewsPim, the members participated in both writing the lyrics and composing the track. Their involvement offers a concrete early detail about the project’s musical direction. The contribution is part of the song’s official introduction, without assigning individual public roles to the members.
The agency describes “Aerotherapy” through the idea of clearing the mind after a tiring day and resting as though lying on clouds. Its relaxed, weightless theme continues the instrumental heard on the promotional website that opened on November 6. The single is the complete version of that initial musical introduction.
SQU4D’s first boy group
oftheblue is the first boy group from SQU4D, the JYP Entertainment division that also manages NMIXX. The single and video establish the project’s first public musical presentation. Its official website carries the pre-release announcement alongside links to music services.
The name draws on “out of the blue,” connecting the project to an unexpected arrival or surprising discovery. That meaning ties together the promotional website and the November 11 material. The confirmed debut milestone remains 2027: “Aerotherapy” introduces oftheblue before that official launch.
