Lời Thề Còn Ở Lại
Piano-led Vietnamese ballad, male vocals. Intimate verse with close-mic vocal and sparse piano; chorus swells with strings and soft pads, kick building subtly on each downbeat. Emotional arc climbs from fragile nostalgia to full-throated heartbreak in the second chorus, then drops to a delicate, almost whispered outro. Roomy reverb on vocal tails, gentle backing harmonies only in the final hook., ballad
