On July 13, a presumed family member posted a video filled with moments of Kang Seo Ha during her lifetime. In the post, she wrote, “I still can’t believe it, unnie. Even while enduring such immense pain, you worried about those around you and about me. Even though you couldn’t eat for months, you insisted on paying for my meals with your own card and never let me skip a meal. My angel, who left us far too soon. Even as you endured everything with painkillers, you said you were grateful that it wasn’t worse, and I felt truly ashamed. My dear sister, you went through so much. I hope you are only happy and free from pain where you are now!”
Born in 1994, Kang Seo Ha graduated from the Korea National University of Arts’ School of Drama and first gained recognition in 2012 by appearing in the music video for Brave Guys’ “Getting Farther Away.”
She appeared in various dramas such as “Schoolgirl Detectives,” “Assembly,” “First Love Again,” and “Through the Waves,” “The Flower in Prison,” and “Heart Surgeons.” She also joined the cast of the new film “Mangnaein” as the lead.
