This is a song where you can really feel the differences in the vocal tones of the line. It’s fascinating how each member sounds like they have a different vibe even when singing the same melody. I especially like how they express emotions naturally rather than forcing them out. Another advantage is that the piano-centered arrangement allows the vocals to be heard more clearly. You can feel the subtle nuances even better when listening with earphones. The lyrics also fit the song's mood really well. That is why I often reach for this song when I want to listen with full concentration.
