There was a vocal trainer for WHEESUNG, who is recognized as a top male vocalist by many people. The vocal trainer is GUMMY, who changed her dream from a pianist to a singer.

GUMMY already made her full album once, but due to the confliction within her former management company, she couldn’t release her album.

Even though she couldn’t debut at that time, her voice skill became very famous among the music industry people. There were so many requests to her to make an album release happen, but it was not an easy choice for her who already had a hard time with the former management company.

That was the time that she met WHEESUNG for the first time. She taught WHEESUNG many ways to express his feeling through his vocal, and played a significant role in finding WHEESUNG’s potential.
