HeeJin is preparing to debut as a solo artist and released the music video teaser for "Algorithm" from her upcoming solo album 'K.'

Starting as a prim and proper princess undergoing etiquette training, HeeJin progressively breaks free from her likely princely confines to pursue her dreams. The narrative vision of the teaser unfolds with HeeJin making her great escape to attend an audition — not as a princess but as an aspiring singer.

Check out the teaser above and stay tuned until her album releases on October 31!
