A classic song by Spitz, where a fresh brightness and a wistful ache coexist in the melody, and Masamune Kusano’s clear, translucent voice strikes straight to the heart.
This piece doesn’t just capture the shimmer of summer; it deftly depicts nostalgia for days gone by and the delicate emotions that waver between reality and illusion.
