Haegang

Those who catch a glimpse of Haegang at Yuunru often mistake her for Im Yeook, and that's exactly what Haegang desires the most.
Haegang's decision to become an Azure Girl of Yuunru was entirely because of Im Yeook. When young Haegang saw Im Yeook for the first time on Unjongga Street, she was instantly captivated. Haegang followed her into Yuunru, and from that day on, she underwent training until she eventually became an Azure Girl.
