Boy group CHAOS will be making their comeback on September 21st with new single "Kiss Kiss".

The boys are returning after promoting single "Racer" in July, which earned them the title of "Macho-Idol" with their tough image. The group takes a different approach with "Kiss Kiss" , which is about a man who is willing to become invisible in order to kiss the girl he loves.

CHAOS' agency stated, "The new single 'Kiss Kiss' and the idea of turning invisible are things that many have probably thought about and can agree with. The exciting funky rhythm and rock-and-roll style are addicting, especially in the chorus. The song features soul and vocal talent, paired with a hard electric guitar sound, that exceed the regular level of many idols."

"Kiss Kiss" was composed by rookie writer Monitor Punch, and the lyrics were written by Lee Young Jun, who has done songs like Norazo's "Superman".

The boys will hold their comeback stage through KBS's 'Music Bank'.
