Mellow ethnic-pop ballad with Vietnamese folk colors; nylon guitar, sáo trúc leads, and warm pads under a gentle mid-tempo groove. Verses intimate and story-driven with soft male vocals, subtle đàn tính plucks; chorus blooms with group child-like backing vocals and hand-hit percussion. Final chorus lifts with octave-doubled lead, airy reverb, and a spacious outro that lets the flute echo like across distant mountains.
