Crush has released a new single, “Seesaw (feat. IU),” with fellow solo artist IU. According to Korea JoongAng Daily, the song went live at 6 p.m. on October 21, 2026, and Crush has said the track might never have come to light without IU’s involvement.
The release follows a separate duet between the two singers, “Creak,” which was announced in mid-October. Crush and IU are both solo artists with dedicated followings in South Korea and abroad, so their pairing has drawn strong interest from fans who follow both of them closely.
IU has been one of the most consistent chart performers of the year. Her September digital single “From This Star” debuted at No. 1 on Melon’s Hot 100, according to The Herald Business, and its B-side, “Dear My Crazy Soulmate,” landed in the No. 2 to No. 3 range on major charts. Chart figures for “Seesaw” had not been published in the coverage reviewed for this report, so it is too early to say how the single will perform.
For fans, the collaboration offers a new angle on two artists who have built their careers on distinct styles. Both singers have often been praised for their vocal control and emotional delivery, and a duet between them is likely to appeal to listeners who follow either name.
