Girl group Rainbow, who just made their comeback with “Tell Me Tell Me” in February, is returning to fans earlier than expected.

DSP Media announced that Rainbow will be releasing ‘Rainbow Syndrome- Part 2’ in June, just after four months since the release of the Part 1 back in February. The group was originally planning to come back in the later part of the year, but they decided to make a bold movement.

Rainbow’s new song will be a great track for the summer, and they are showing a strong will for the intense competition with great number of many other singers who will be coming back as well.
