Slow duet ballad with violin, acoustic guitar, and piano; steady 6/8 sway, intimate and romantic. Verse 1 stays sparse with close-mic dual vocals and soft piano, pre-chorus lifts with bowed strings and breathy harmony tails, chorus opens into wider duet lines with sustained violin and gentle guitar strums. Add brushed swells, reverse piano pickups, and a final key-change feel. Warm, cinematic, close and tender mix.
