Park Ha-Sun's agency KeyEast told News1 that Park's younger brother died of acute myocardial infarction on the 12th. The funeral cortege leaves Friday, November 14. Park Ha-Sun and her husband Ryu Soo-Young reportedly left the mortuary in great sorrow.

Park's brother was two years younger than her and reportedly had developmental disabilities. She once mentioned her brother at JTBC's talk show, "Kim Je-Dong's Talk to You" in 2017.

At that time, Kim asked her what came to mind when she thought of a police officer. She replied, "My brother is a little sick. If you don't lock the door, he just leaves the house. I have memories that the police always found my brother every time he left home."

As she revealed her sisterly love on the show before, netizens mourn for Park's brother and convey words of consolation and support.
