Key points

'Insomnia' drops at 12 a.m. KST on October 26 across streaming platforms, with the music video going up at the same time on SM Entertainment's YouTube channel, SMTOWN.
It's a new lane for RIIZE: an acoustic pop song with no performance, relying entirely on the voices of all six members.
Lyricist Kim Ina wrote about thoughts of one person that grow stronger as the night deepens, and the tangled emotions that follow.
RIIZE's previous release, the second mini album (EP) from June, became the group's fourth million-seller.

RIIZE's pick for its fall comeback is a single called 'Insomnia.' It arrives at 12 a.m. KST on October 26 and will be available on Korean streaming services as well as global platforms like Apple Music and Spotify, plus China's QQ Music. The music video goes live at the same moment on SMTOWN, the YouTube channel run by the group's label, SM Entertainment.

The direction here is clear. The genre is acoustic pop, and the sound is hushed with a lonely edge. Unlike the group's earlier dance-forward title tracks, this one strips out stage performance and leaves the song's center of gravity to the six members' restrained, yearning vocals. According to the agency, it's a musical color RIIZE hasn't tried before.

Lyrics come from Kim Ina, one of K-pop's best-known lyricists. Built around the feeling of a sleepless night, the words trace how thoughts of one person sharpen as the hours drag on, and how a web of different emotions branches out from there, all in a calm, measured tone.

The backdrop is a strong summer. RIIZE put out its second mini album in June, promoted with the title track 'Do Your Dance,' and the record made it the group's fourth million-seller. After a summer of high-energy performances, the group is back about four months later with a mood-driven song suited to the season, and it's being framed as a preview of where the group's sound may be heading.

In Korea right nowMajor Korean outlets all ran the news on October 19, focusing on how RIIZE, known for performance-heavy releases, is pivoting to a vocal-driven autumn song. Two things are driving the buzz: the quick change of mood right after a hit summer run, and the news that Kim Ina is writing the lyrics.
