STAYC is returning with an autumn vibe.

On October 18, High Up Entertainment announced, "STAYC will release a new digital single titled '...l' on October 30." They also unveiled a teaser image motion related to the upcoming release.

The teaser heightened fans' anticipation. In the video, a kitschy pink phone appeared, and a message popped up asking, "Aren't you curious about me?" and "Is this enough?"

The empty phone keyboard also drew attention. The letters "GPT" were displayed, raising curiosity about the meaning behind the word.

'...l' marks their comeback approximately three months after the release of their first full album, 'Metamorphic.' The single promises to present STAYC's distinctive autumn sentiment.

Following the single release, STAYC will open a pop-up store, 'ONLY 4 SWITH,' to commemorate their 4th anniversary. In February next year, they plan to release new music, followed by their second world tour kicking off in April.

STAYC's '...l' will be officially released on October 30 at 6 p.m. KST.
