Solo artist/actor Lee Eun Sang teased his debut with Brand New Music's upcoming new boy group.

On December 31, Lee Eun Sang unveiled an epilogue film to his 2nd solo single album, 'Beautiful Sunshine'. In the film, Lee Eun Sang wakes up from a dream wearing the same pajamas he wore at the end of his "Lemonade" MV. Looking around momentarily, he then runs and joins a group of five boys, who welcome him as they walk on. Lee Eun Sang also leaves a cryptic message with his narration, "Beyond the karman line, I unite with you." 

Meanwhile, Brand New Music is currently preparing to launch a new boy group led by Lee Eun Sang in the first half of 2022. More information regarding the team's debut concept, date, and more will be revealed soon.
