Cha’s death is the third inside three months of a young South Korean performer. In October, outspoken 25-year-old singer Sulli died shortly after leaving a note that hinted at depression. Last week, 27-year-old K-pop star Goo Hara was found dead at her home in Seoul.

Cha emerged at the forefront of the South Korean entertainment scene only in the past couple of years. He was a member of Fantagio’s actor group Surprise U, and had starred in dramas including “The Banker,” and “Miss Independent Ji Eun 2.” He had recently appeared in MBC drama “Love With Flaws.”

Within the last day, Cha (real name Lee Jae-ho) posted a picture of himself on Instagram posing with a white mug and looking moodily at his phone. “Everybody, watch out,” he wrote.
