Reflection of a Happy Song

When the hero finally finishes his quest of saving the babies of lulu, which was Mikau's last favor he asked with his final heart beat.
a happy, heart warming song plays inside the hero's head making the hero cry gently and at the same time having such a strong emotion that made the hero so confused and to ask himself:
“What is this feeling? I don’t understand at all”
And the answer was that Mikau’s tears of happiness were reflected through the hero’s face. And that marvelous tune that the hero was only able to listen was a way that Mikau could say to him “thanks for everything you have done, now I can rest in peace in a happy place thanks to you and keeping with me the image of Lulu’s sweet voice and heart warming smile.”
