Notice that how in every comeback there are always flowers either in or around the cassette tapes?
But, in this comeback... there are no more flowers ㅠㅠ
It's just the tape surrounded with soil.
Ohhh just what could it mean?
If the tape is being buried then it could signify as the start of something or the end of something.
(This is just my theory, you're free to share yours in the comments. Let's be emo together ㅠㅠ)
