P1Harmony is preparing for a new release titled 'BLOW UP' and has unveiled a promotional trailer for their comeback, while also releasing a Japanese edition of their 'UNIQUE' mini-album featuring two additional tracks. The group continues to promote their music despite member Jiung stepping back from performances due to an ankle injury and his absence from the KCON LA 2026 event, and member Keeho drew attention for briefly engaging with a post by ITZY's Yuna on Instagram.
