On September 13, GFRIEND members SinB, Yuju, Eunha, Yerin, Sowon, and Umji held a Naver V Live broadcast for their fans to commemorate the release of their repackaged album Rainbow. During the show, they talked about their new album, songs, and stories behind their comeback.
Following their previous release Love Whisper, GFRIEND came back within three weeks with their new repackaged album. SinB said, While we were promoting Love Whisper, we prepared this repackaged [album]. We didnt know this album would be released within three weeks. Yuju showed excitement for the new song, saying, My mouth was itching [to sing the new song].
GFRIENDs new repackaged album contains two new tracks, title track Summer Rain and Rainbow, in addition to previously included songs.
Yuju addressed fans questions about why a track titled Summer Rain was being released at the beginning of fall, and revealed, Summer Rain is a song that looks back on summer memories, so its a good song to listen to in the fall. Eunha added, It is a song about beautiful love that is unpredictable as the summer rain.
