Crush surprised fans on November 11 by posting a live duet of his new song “삐그덕” with his girlfriend, Red Velvet’s Joy, on his official YouTube channel — a fresh take on the track that originally featured IU.
The video, titled “Crush (크러쉬) - 삐그덕 Live with 조이 (JOY),” was uploaded to Crush’s YouTube channel on the evening of November 11 and shared across his social media accounts, according to OSEN. It shows the couple sitting side by side and singing the song together, swaying gently to the rhythm as they trade lines.
Notably, the video never shows the couple’s faces. The camera frames only their upper bodies, with Joy cradling Crush’s pet dog Dooyoo in her arms throughout the performance. Even so, the quiet, shoulder-to-shoulder performance was enough to send fans into a frenzy, with many saying the clip felt more swoon-worthy than any of the song’s other challenge videos.
“삐그덕” was released on October 21 as Crush’s new single. Crush wrote and composed the track himself, describing it as a love song that looks at a clumsy, creaking romance through an affectionate lens. IU lent her voice to the original recording as the featured artist, and the pairing drew plenty of attention at the time.
The IU collaboration also sparked a round of playful teasing online. Because Crush was publicly dating Joy while singing a love song with IU, netizens joked that the whole country was watching the situation awkwardly, in what became known as a “the whole nation is watching” reaction.
To promote the song, Crush has been filming live collaboration versions with a string of different artists, including a recent version with Ryeojin and Chan. All the while, fans had been openly hoping for the one duet that mattered most to them: a version with Joy herself. The surprise upload answered that wish directly, and it arrived on Pepero Day, November 11, a date Koreans associate with sweet gestures between couples.
Fan reaction was immediate and effusive. Commenters praised the blend of the two voices, with one writing, “We want an official duet song, too,” while another declared, “The Joy version is truly the best.” Others urged the couple to release the duet as an official track and jokingly asked for a hundred more songs together. Several fans also asked the pair to duet Crush’s earlier hit “내입술 따뜻한 커피처럼” next.
The duet carries extra weight because of the couple’s history. Crush and Joy first worked together on Crush’s May 2020 single “자나깨나,” which featured Joy’s vocals. Dating rumors surfaced in August 2021, and both sides confirmed the relationship, making them one of K-pop’s most high-profile public couples. Five years on, they are now in their sixth year of dating, and the new video is their most public musical moment together yet.
Crush, born in 1992, debuted in 2012 and has built a career as one of Korea’s leading R&B singer-songwriters. Joy, born in 1996, debuted with Red Velvet in 2014 and has been active both as a singer and an actress.
Crush shared the video without any accompanying message, according to Sports Seoul, letting the performance speak for itself. That restraint sharpens the contrast with the song’s rollout so far: while the IU-featured original arrived as a polished studio single, the Joy version is deliberately casual, with the couple’s dog in frame and no attempt to stage a formal performance. Fans have read that intimacy as the point, saying the stripped-back setting suits a song about a love that does not run smoothly.
No official audio release of the Joy version has been announced. For now, the duet lives only as a live video on Crush’s YouTube channel, where fans are already treating it as the definitive version of the song.
