I remember when Song Joong Ki hit it big with Nice Guy and then even bigger after military service with Descendants of the Sun there was a lot of coverage about his background. He had one of the highest entrance test scores and graduated from Sungkyunkwan University before entering actor. Then people found out he comes from an academic family background and his older brother majored in Chinese at Beijing University. Now his younger sister adds to the family academic pedigree by graduating from Seoul National University School of Medicine and becoming a doctor. The siblings attended her graduation and took a picture and just at the two oppas beaming with pride!
