After wrapping up the promotion for their comeback track “A” for a month, Rainbow returns to the music scene with a new song and concept.
Their new song “Mach” will be released on October 21. It is a song about a girl experiencing love at first sight and her desire for the lover to approach her quickly.
DSP Media commented, “They’ve only shown innocent and sexy sides. They will show an image that will be upgraded. They will transform into the sexy dominatrix image.”
