[All] Blue and Gray is so sad and brings tears to my eyes

It's a really sad song because it honestly captures the depression, anxiety, and emptiness the members felt during the Corona period.

Blue represents depression and gray represents emptiness, I can feel it well.

The voice is quiet and calm, so it sounds even more painful.

I feel really sad and sorry for the lyrics that say, "I don't know where it went wrong."

It seems like a story about fighting against an unknown darkness, not just simple sadness.

It's a sad song with a gentle guitar and piano that goes well with the members' vocals.
