Behind the Track (4th Album) #7 — 始発を二人で (The First Train, Together)

The four-album story closes on a song where two people open the curtains and watch the sky turn white. Far away, the rails ring — the exact sound heard alone in the 2nd album’s 始発が来る.
The scene it came from
That day there was nowhere to ride to, so no one boarded; today, no one needs to. Hearing the same sound with a different heart — that is the distance of four albums. And the coffee: in the 2nd album one of two convenience-store bags went unused; in the 3rd, one of two cups going spare was okay; in the 4th, neither cup is left over. The same objects, measuring the distance between albums — this is the final mark on that ruler.
Sound notes
86 BPM, D major — the only major key on the album. It continues the tradition of each record’s final track opening into major (A major on the 2nd, E major on the 3rd), but this time the reverb doesn’t lift away — the song starts inside morning light. For the first time in the series, the night ending is something to regret.
One line
朝が敵じゃなくなる日が 本当に 来るなんて — I never thought the day would come when morning stopped being the enemy
Not a story where the fear disappears — a story that confirms morning still comes after saying you’re scared. The tetralogy closes here: seeing the first train off, and still not going to sleep.
