“I still can’t believe it, unnie [Korean for older sister]. 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,” the family member wrote. “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!”
