“It took a huge amount of courage to speak out,” NewJeans have told the BBC in their first interview since a court blocked their attempt to leave their record label, in a case that has rocked the K-pop industry.

“This fight is necessary. Although it will be extremely difficult and arduous, we will keep doing what we have done so far and speak up,” said Haerin, one of the band’s five members.

“We thought it was important to tell the world about what we’ve been through. All the choices we’ve made so far have been the best choices we could have made,”

NewJeans looked invincible in the charts when they launched what was an unusual rebellion in the high-pressure, tightly-controlled world of K-pop. Hanni, Hyein, Haerin, Danielle and Minji stunned South Korea and fans everywhere with their decision in November to split from Ador, the label that launched them.

They alleged mistreatment, workplace harassment and an attempt to “undermine their careers”, which Ador denies. It sued to enforce their seven-year contract, which is set to expire in 2029, and sought an injunction against any commercial activities by the group.

On Friday, a South Korean court granted it, ordering NewJeans to stop all “independent” activities, including song releases and advertising deals, while the case was still under way. NewJeans has since challenged the injunction in court.

Friday’s ruling was a “shock”, the group told the BBC. “Some people think that we’re famous enough to do whatever we want and say whatever we please. But the truth is, it’s not like that at all,” Hyein said. “We held it in for a long time, and only now have we finally spoken up about what we think, what we feel and the unfairness we’ve experienced,”
