Kim Jae Hwan is back with a new album!

On September 5 KST, the solo artist unveiled his 5th mini album 'Empty Dream,' featuring title track "Back Then."

"Back Then" is a mid-tempo combination of pop, rock, and R&B and expresses the relatable emotions of someone looking back on a relationship that ended and finding themselves missing how things once were. In the music video, the idol is seen acting out this feeling of loss, while other scenes show him playing guitar with a band, a subtle nod to his pre-debut days as a busker.
