A snippet from the studio

Agency P NATION posted a teaser video on its official social media on Oct. 15. It shows Crush and IU working together in a studio, and a snippet of the new song with both vocals plays at the end.

On Oct. 16 an image followed with the Korean title, "SEESAW Feat. IU" and the release date.

Seven years in, their first track

Their ties go back to 2019, when each appeared as a guest at the other's solo concert. In 2022 Crush was a guest on IU's music talk show "IU's Palette."

Until now they had shared only stages and screens; this is their first release together as a song.

Crush's first in 14 months

It is Crush's first new music in about a year and two months, since the EP "FANG" last August.

IU put out the two-track digital single "Unknown Planet" in September after postponing her sixth album for health reasons.
