JYP Entertainment will be taking action against the 'IlBe' user who threatened TWICE.
On the 2nd, a post came up on the site with the title, "TWICE has abandoned Korea and is earning a ton of money in Japan". The post included a photo of the line of Japanese fans who'd come to see TWICE. The poster wrote in the post, "Yeah, money is good. Money is the best. Never come to Korea. I'll be waiting for you at the airport with 10 L of hydrochloric acid."
JYP Entertainment said, "TWICE is coming back to Korea on the 3rd, and we have placed security at the airport. We are going to track the IP address of the poster, figure out their identity, and take strict legal action."
