Kennith

He basically called Korea gay and he didn't like the people (he said all of this like 2 years ago). He wrote that he was sacrificing a few years of his life in Korea to make enough money and go back to the US and live comfortably. He didn't know the Korean national anthem...eh, netizens are a bit overboard but I can understand why they would be upset. The backlash he got caused him to leave the group.
