In 2018, the singer filed a lawsuit against her ex-boyfriend, Choi Jong-bum, for allegedly threatening to release a sex tape of the two of them having intercourse.

In May of this year, the musician was found unconscious by her manager after a suspected suicide attempt. The day before, she posted the one-word message "goodbye" on her Instagram account, according to the South China Morning Post.

After recovering in hospital, the singer apologized for her actions, saying "I am sorry for causing concerns and a commotion," according to the Korea Times.

"I had been in agony over a number of overlapping issues," she added. "But from now on, I will steel my heart and try to show up healthy."

Recently, Hara had staged a comeback, releasing the single "Midnight Queen" for the Japanese market, and embarking on a solo tour across Japan from November 14-19, the South China Morning Post reported.

Hara's death comes one month after fellow K-Pop star Sulli died at the age of 25. The singer, who was part of the K-pop girl band f(x), was discovered at a house in Seongnam, in Gyeonggi province, on October 14.
