Group B1A4 CNU has released a cover video for member Sandeul's solo song 'Diary'.

On the 16th, WM Entertainment, the agency, surprisingly released a video of Sandeul's 'Diagonal Line' covered by CNU through the official YouTube and SNS channels. CNU, who celebrated his birthday on the day of the release, is receiving an explosive response to the surprise gift he prepared for his fans.

‘Different Line’ is a song from B1A4 member Sandeul’s 2nd mini-album ‘Good Weather’, released in 2019, and has been loved by the overall lofi atmosphere, lyrical piano sound, and autobiographical lyrics. It is especially meaningful because it is a song that CNU wrote and wrote as a gift.

In the published video, CNU is wearing a sensual black-and-white screen suit and exuding a sensuous aura, drawing attention. The soft, charismatic eyes and the more mature CNU's emotional acting outstandingly revive the dark and lyrical mood of the original song, further enhancing the immersion as if watching a piece of emotional noir.
