스물다섯, 스물하나
10cm
10cm's contribution to the *Twenty-Five Twenty-One* soundtrack is deliberately warm and analog: strummed acoustic guitar up front, brushed drums, tasteful strings that arrive only when the chorus needs lifting, and a mix that keeps everything slightly soft-edged, as if the song is being remembered rather than performed. Kwon Jung-yeol's voice is the reason 10cm works in this register — a light, slightly nasal tenor with a boyish crack at the top of his range that reads as sincerity rather than technique, and he sings the melody almost conversationally, letting the biggest notes stay unpolished. Lyrically it's about a particular kind of youth: the age when everything is felt at maximum volume and nothing yet has consequences you can't survive, addressed backward from a vantage where that time is gone. The drama it accompanies is set during Korea's IMF crisis, which gives the nostalgia a specific national texture — a generation whose adolescence was interrupted by circumstances they didn't cause. It's the song for a walk past your old school, or for the moment on a spring evening when the weather is exactly the temperature it was when you were eighteen.
