Singer Gummy has released her new song "Perfect World," which contains her own personal confession.

"Perfect World" is a song that expresses love and gratitude felt toward someone who is precious to her.

The warm melody blends well with Gummy's powerful vocals.

Through lyrics she wrote herself, Gummy delivers a heartfelt confession to the person who has made the world beautiful.

It also feels like a confession dedicated to her husband, actor Cho Jung-seok, and their children.

Starting next month in Seongnam, Gummy will embark on a national tour spanning Busan, Daejeon, and other cities.
