Ga-In in the latest episode of Strong Heart. She was rather over-looked from Nichkhun and Bom's confessions. But her style is never over-looked. Sadly, I've only found her accessories after a quick look.
Her ring is the House of Harlow 1960 Sunburst Cocktail Ring, which was previously found. The bracelet is a Marc by Marc Jacobs Keeper.
