According to Nate, Kang's family shared a message about her death on her Instagram account on Monday.

"I still can't believe it, sis..." reads the message. "Even though you were enduring such great pain, you were still worrying about those around you, worrying about me..."

"You hadn't eaten properly for months, yet you always insisted I pay with your card and wouldn't let me skip a meal. My angel, who left us too soon..."

Many in the South Korean entertainment industry subsequently confirmed that Kang had kept her illness private, continuing her work despite her suffering.

She participated in filming, appeared in commercials, and even completed her final film "In the Net," which is scheduled for release later this year. Colleagues and friends described her as always professional, with a smile and remarkable strength, despite the constant pain she endured.

Following the announcement of her passing, fans and fellow artists expressed their deep condolences on social media.

According to Malaysian news outlet Hype, Kang's funeral will be held on Wednesday, with her final resting place at her family's burial site in Haman, Gyeongnam Province.

Born Kang Ye Won in 1994, Kang Seo Ha starred in several notable films, including "Flowers of the Prison," "First Love Again," and "Nobody Knows."
