On October 5, Dingo Music released a video of Kim Feel's 'Killing Voice' on their official YouTube channel. In the video, Kim Feel stated, "First, I will deliver the songs that many of you have loved, and then I will deliver the songs that I love a lot. I hope they will be to your liking." Kim Feel began by singing portions of his hit original soundtracks, including "Someday, the Boy" for 'Itaewon Class', "Youth (Feat. Kim Chang Wan)" for 'Reply 1988', and more. His vocals deeply touched the hearts of listeners and his deep emotions were relayed through his songs.

He then performed his ballad track "Like The FIrst Moment I Met You", which was recently released on September 29. This song conveyed the emotions perfect for the autumn season, marking Kim Feel's return to the music industry as the 'vocal king'.
