As the cold night air nipped at his exposed skin, Diluc glanced up at the night sky for a few moments, admiring the peaceful serenity of the scenery in front of him. Then, he glanced back down at the golden white flute.

"This... doesn't look so hard..."

With that being said, Diluc brought the instrument up to his mouth again and gently blew into it, producing a slightly off, but mostly proper note. Despite the cold weather, he didn't hesitate to continue practicing.
