[Edaily Starin YUN GI BACK Reporter] Donghyun of the group KickFlip has teamed up with British singer-songwriter Etham to expand his musical horizons as a vocalist and singer-songwriter.

Donghyun released the single “Breathe,” a collaboration with Etham, at 1:00 p.m. on the 14th. The collaboration drew attention as it brought together Donghyun—who has showcased a clear and lyrical tone through cover content and various performances—and Etham, whose strength lies in his emotive vocals.
In the released live clip, the harmony between their voices stood out particularly well. Donghyun’s refreshing voice and Idam’s soulful vocals blended seamlessly over a simple arrangement centered on guitar playing, bringing out the original song’s emotional depth. Fans also reacted positively, noting how well the two voices complemented each other.
“Breathe” is a medium-tempo acoustic pop song that unravels the overwhelming and complex emotions of unrequited love. It conveys the desire to be someone special to the other person—despite the fear of having one’s feelings discovered—through delicate guitar riffs and piano sounds.
A key point to note about this collaboration is that Donghyun did not merely participate as a vocalist. By co-writing the song with Lee Dam, he continued his journey of actively shaping his own musical identity.
Since his debut, Donghyun has participated in writing and composing several Kickflip tracks, including “FREEZE,” “The First Song I’ve Ever Sung,” “Twenty,” and “Stup!d.” This collaboration with an international singer-songwriter is significant in that it marks an expansion of the creative experience he’s gained through the group’s activities into an external project.
In particular, “Breathe” with Lee Dam can be seen as a milestone in Donghyun’s journey to expand his horizons beyond being a member of Kickflip and establish himself as a musician with his own distinct vocal tone and creative capabilities. The fact that he engaged in direct musical exchange with an international artist has also drawn attention to his future collaborative endeavors.
