The song is actually a pre-release single for a mini album the singer will be releasing later next year. It's titled "Gwae Soo", which in Korean, can either mean a mythological beast, or a ringleader. The song also features Kang E Chae and Go Sang Ji.
Fellow former 'Superstar K' artists like Roy Kim and Parc Jae Jung took to their SNS accounts to promote Kim Feel's first new song release in a year and 5 months. Look out for it, being released November 8!
