This song is everything I can wish for in a winter ballad.  The piano in the instrumental track is great (very Naul-like where it has the Korean CCM-vibes mixed in with the classic ballad feels), the strings kicking up by midway through the song, eventually leading to a key change.  Instrumentally this checks off all the boxes I need with a ballad.

Taeyeon’s singing in this reminds me of her earlier year style ballads (만약에 vibes here).  With the lyrics and how she sings, it is a good emotional gut punch to round out the ballad as a whole.
