P1Harmony is preparing for their comeback with a new mini-album 'Harmony : All In' and released more teaser photos.

On May 25 at midnight KST, the boys released additional teaser photos where they show off their charisma. The members display their individual charms against the wavy blue backdrop, making it look like they are underwater.
