Group Sunny Hill will be coming back with a ballad titled, "Goodbye to Romance."

An official commented that unlike their usual concept-themed songs, they will be making a comeback for the first time with a ballad.

Their new song features a chorus and the piano along with their beautiful vocals. Unlike their usual performances with fun outfits, they plan to bring a calm and easy going ballad.

Their music video is also different as they used a new method called the 'one take' method where there are no cuts and they film it just once through with no edits.

Their new album and music video will be released on December 14.
