It is really a thrilling new combination. 'WJMK', a crossover of different girl groups with different charm, rather than a unit within a single girl group, was born.
Seola and Luda from WJSN, Doyeon and Yoo-jung of Wiki Mickey, deliver the charm of 'Cutie Girl Crush' in this special unit group WJMK.
'STRONG' is a hip-hop dance song with a distinctive flute melody and cool sound. It is fun to listen to various vocals of Seola, Luda and Doyeon with the girl crush rapper Yoo-jung.
