The first unit of the group WJSN, Jjokkomi, celebrated their 1st debut anniversary. Jjokkomi, composed of Subin, Luda, Yeoreum, and Dayoung, released the single ‘Hmph!’ on the 7th of last year and fired the signal for their successful debut with a fresh concept.
As this is WJSN’s first unit sortie, Jjokkomi attempted a radical transformation. Jjokkomi’s facial expressions and easy-to-follow, yet witty choreography that fit perfectly with the title of ‘Hmph!’ created a ‘Hmph! Challenge’ through various social networking services (SNS), and the unique bouncing charms of the four of them on every stage, and it also proves its extraordinary popularity by rising to the top of real-time portal site search terms.
