Editor's note: In an industry that values cookie-cutter conformity, Hyolyn marches to her own beat: she left Sistar to go independent, she even founded her own production company, she shakes off negativity like a queen, and of course there’s that unique voice. Both powerful and soaring, Hyolyn’s voice should be declared a national treasure by South Korea! If you agree, spend some time in this gorgeous collection and get yourself a few Hyolyn wallpapers today!
