On August 2, 2018, photos of Hyuna with Pentagon's E'Dawn were released. Cube Entertainment denied rumors that they were dating, however, she and E’Dawn held an interview with Yeonhap News later that day, admitting to their relationship which began in May 2016, after they had got to know each other through their project group Triple H promotions. The company responded to Hyuna's confirmation of the dating rumors by cancelling all previously planned performances for Triple H, on-air appearances and fan events including a fan meet-up that was scheduled on the next day. Fans were divided in reactions to the event, with some calling for E'Dawn to be removed from Pentagon, and others focusing on how the company mistreated her and E'Dawn after releasing the scandal, rather than on their relationship. On September 13, Cube Entertainment announced that they would be terminating their contracts, citing that they could not "maintain trust" with them. However, the company announced that they would still remain in discussion with both of them until further notice. Cube Entertainment cited “loss of trust” as a reason saying "After much deliberation, we've concluded that the trust between the company and the artists had been damaged to a degree that it cannot be restored, leading us to believe expulsion is necessary," in its official statement. On October 15, Cube Entertainment officially confirmed Hyuna's departure.
