Rune, a member of the group Darkbee (DKB), showed his singing skills as well as delicate acting.

Yesterday afternoon, Rune's vocal cover song was released on Darkbee's official YouTube channel and SNS.

In the released video, Rune covered CIX Bae Jin-young's "Hard to Accept the End" and presented a unique charm with a beautiful voice that stimulates emotions. It also caught the eye with its appealing facial expression and delicate emotional lines. The visual that seemed to have ripped out of the cartoon contributed to the improvement of the completeness of the video.
