I vaguely remember hearing this dating news years ago but back then neither were as well known stars are they are today. It’s still sad thought to report that actor Park Sung Hoon and actress Ryu Hyun Kyung have broken up after 6 years of dating. They met on the stage production of Almost Main and started dating afterwards. Reports of their breakup was swirling after she changed her username which used to be boxumum and he was boxabum which referred their dog Box. Both are in their late thirties and as the saying goes once the dating relationship and age hit a certain mark and taking the next step isn’t on the table then it’s best to part ways.
