"Yeul's Theme" is Paddra Nsu-Yeul's leitmotif from Final Fantasy XIII-2. It is an acoustic guitar tune composed by Naoshi Mizuta with lyrics performed by Joelle. Mizuta wanted to create a pretty and poignant ballad. The piano ad-lib during the interlude was performed by Mizuta's favorite pianist, Febian Reza Pane. An arrangement called "Noel & Yeul ~The Promise~" plays in Lightning Returns: Final Fantasy XIII.
