Vietnamese sad pop ballad with slow 6/8 sway and gentle guitar arpeggios, soft brushed percussion, and a restrained piano line; verse stays intimate and close, pre-chorus lifts with rising harmony stacks, chorus opens into aching singalong phrases with doubled lead and a few breathy ad-libs. Add reversed swells before chorus, a bell-like turnaround between lines, and a final chorus with string pad bloom. Mix is warm, tender, and close-mic with a nostalgic sheen.
