The duet, "Say I Love U," will be released on May 6, marking his first comeback in 8 months since his last single, "I Like This." The lyrics of the duet will relay the sweet emotions of a lovey dovey couple that is confirming love for each other.
A rep from the agency stated, "The vibe of the song was upped one level thanks to the sweet voice of Dal Shabet's Woohee, who is featuring, and the warm vocal tones of Jeon Young Do. Yet another Dal Shabet member besides Woohee is giving her help. Please look forward to seeing who that next person is."
