C9 Entertainment's rookie boy group EPEX is gearing up for the release of 'Prelude of Anxiety Chapter 1. 21st Century Boys'.

Shortly after releasing individual concept photos for Baekseung and Jeff, EPEX unveiled another set of concept photos for member Keum. In the images, he sports bleached blond hair and a number of eyebrow and ear piercings, creating a stark edgy contrast to his sleek uniform look.

Meanwhile, EPEX's first comeback of 2022 with 'Prelude of Anxiety Chapter 1. 21st Century Boys' is set for April 11 at 6 PM KST.
