The 'Buying Hardships' crew had been in Brussels in Belgium for their variety show. While they were moving, Park Joon Hyung was approached by a group of people who seemed to want to greet him in a friendly manner.
However, it turned out they were trying to rob him, and he fought back, resulting in the group yelling curses and racist slurs. He almost exploded, fighting back, but the rest of the cast as well as the staff of 'Buying Hardships' managed to contain the situation.
You can check out the clip below and read his reassurance (in Korean and English).
