U-Know Yunho of TVXQ! has officially begun the countdown to his comeback.

He will release his first full-length album I-KNOW on November 5, with the pre-release of one of its double title tracks, Body Language, set for October 13.

A Feel-Good Dance Track

Body Language is a dance song that blends blues, funk, and retro-style hip-hop — genres beloved across generations. The track delivers a refreshing, feel-good vibe, enhanced by Yunho's upbeat and energetic vocals. Its lyrics convey a unifying message: enjoying the moment together through the universal language of dance.

World-Class Choreography

The choreography was created by world-renowned choreographers Bata from WeDemBoyz and Riehata from RH Tokyo. They visually interpret the song's concept of "communication through body movement" with precision and artistry.

A key highlight of the performance lies in Yunho and his dancers exchanging gestures and movements throughout the stage. His agency noted, "The performance will offer a unique sense of visual enjoyment."

Cinematic Comeback Teaser

On October 10, Yunho also dropped a "spoiler film" on social media, where he plays dual roles — a character giving a secret mission and another executing it. The video, with its sleek editing and fast-paced narrative, cleverly weaves in visual hints tied to the I-KNOW album concept, amplifying anticipation for his return.

I-KNOW will be released on November 5 at 6 p.m. KST across major music platforms, alongside the physical album.
