I do feel I have to put in some kpop here.
This was a release from one of my favourite groups, Lovelyz. It wasn't their last title track, but is has a valedictory quality nonetheless- perehaps because they new they were nearing their disbandment.
The lyrics are about looking back and remembering a past love - that kind of reflection has been an important part of my life.
The rearrangement of the song for this performance is one I very much like, and I think the members look so pretty here too; performance and visuals matter in kpop!
