K-rnb song/group?

If you use Spotify you know that they have some little previews of songs and they even put the name of the genre so you can explore it. I just saw this little video preview that was titled k-rnb and it showed a super handsome guy with an oxygen mask on. At the moment I couldn’t open it so I waited but when I opened the app again I had lost it :( I’m really curious about this guy, not sure if he was in a group or not.
