Singer-songwriter Maeng Yuna (29) has passed away. 

On January 8, JH Entertainment announced, "On December 26, Maeng Yuna has passed away at her home from a heart attack," and explained, "We were unable to share the news sooner because it was year-end time and things were overwhelming. A funeral took place with close peers."

The agency added, "She was preparing the 3rd album to be released in June and showed motivation after being invited as the music department professor for a university. Besides from stress from music producing, she did not have any specific illness. It's unbelievable."

Maeng Yuna debuted with "Waltz of Spring" in 2007. Since then, she actively promoted as a singer-songwriter. In April 2018, she released her 2nd album.
