I'll be re-reacting to SHINee's title track for the Story of Light: Epilogue album which is the 4th part of their Story of Light albums. This song is at the same time a great song but at that time it felt a bit sad because it was when most of them were going to enlist in the military. Everyone shows off their vocals, I don't believe there are actually any rapping in this song. The video is nice and simple and shows a lovely palette of colours.
