01. In 2016, prominent Busan couple, Choi Sung Hee and Kim Yoon Suk, disappeared in the thin air, just 6 months into marriage. There were last seen in CCTV entering their apartment, but none of them were ever seen leaving their apartment. Their grocery was untouched and they left behind a dog. There was no sign of them in CCTV even though there were so many of them. #creepy #unsolved #mysteries #mystery #dissappearances #wtf #shocking #horror
