The 2nd single from timelesz under their new lineup. This work is the first pop ballad single from timelesz under their new lineup. It is a song characterized by a beautiful yet fleeting melody and lyrics that compare the miracle of meeting to fireworks, and it is a love song with a bittersweet yet warm theme: "Fireworks fade away, but the memories we shared together live on in our hearts." It is a song that adds color to summer memories, so please look forward to it. The Regular Edition contains "Compass" and "Yowa no Tsuki" as B-side tracks.
