The song changes and the song is sadder than the first but also hopeful.Pain hears the noise sitting on the rooftop of one of the nearby buildings. " well what a wonderful melody..." He hums the rest of the song.
(a girl sings it sorry couldn't find a girl singing it)

For some reason this hits pain's heart bringing back memories of Sirena..... Of her her leaving for war when you two split ways, the last time you saw her.
