BTS star Jung Kook says the band's solo projects will make them more powerful when they reform.
The superstar boyband are currently on a break while some members serve in the South Korean military.
It's left the rest, Jung Kook included, free to launch their own material - and he's just released a single, Seven.
He told Radio 1's Live Lounge the solo work would allow each member to explore their tastes, and then make sure they come back stronger when they reform.
Jung Kook performed Seven and a cover of Oasis' Let There Be Love when he appeared on Radio 1 earlier.
He also spoke to hosts Rickie, Melvin and Charlie about his solo material and the future of BTS.
"It's good that we all have time to grow individually through our solo projects that reflect our own tastes," he told them through a translator.
"After this time of personal growth our synergy will be much more powerful as one team.
"I can't wait to perform on stage with all our BTS members."

Jung Kook's appearance on Radio 1 caused hysteria among BTS fans, with the hashtag #JUNGKOOKLIVELOUNGE quickly going to the top of Twitter's trends.
And he also spoke in English to send a message to his fans - known as the BTS Army.
"I know how much love and support you're sending me and I can't thank you enough," he said.
"Love you all."
