Playful indie-pop with nervous energy, mid-tempo (90–100 BPM), male vocals. Verses: intimate, slightly tense, building up. Chorus: bright, catchy, but with a hint of unease — as if laughing through awkwardness. Instruments: electronic synths, soft guitar, punchy percussion, subtle bass. Dynamics: from almost whispered verses to fuller, more urgent chorus. Atmosphere: train car, grey windows, awkward human moment, tension between smile and fear. Mood: playful, slightly nervous, warm but on edge.
