Dr. Je-Gyu Kim was a doctor and a fertility expert residing in Seoul, South Korea who was a good friend of Mr. Paik. When Mr. Paik's daughter Sun and her husband Jin came in for an examination to see if they were able to conceive a child, he informed them that they were unable to do so due to Sun having advanced endometriosis, scar tissue blocking the fallopian tubes. He states that even with surgery, the chances of conceiving were impossible. Upon hearing this, Jin accused Sun of having prior knowledge of this, to which Sun sarcastically stated that she had done so to trap the son of a fisherman. Jin became frustrated and threw all of Dr. Kim's papers from his desk to the floor and stormed out.
