Jung developed an interest in guitar after watching his father play. He found his father's guitar playing more interesting than piano, which he was already learning.Jung's father taught him the basics, and after learning the basics, he developed his skill greatly just by trying to play what he heard.When he struggled he would study online videos.Jung came to play fingerstyle when his father discovered the fingerstyle technique on the internet. His first 'idol' was guitarist Kotaro Oshio, from whom he developed interest in fingerstyle.At first, Jung's mother and grandmother disapproved of the 'noise' that Jung and his father continuously created, but they came to understand it as his gift.
