@ive.in.my.heart: "Gongjuz" is the popular duo nickname used by fans for Rei and Wonyoung from the girl group IVE. The term comes from the Korean word "gongju" (공주), which translates to "princess". Fans gave them this duo name due to their visual synergy, regal auras, and their close, endearing friendship. #ive #rei #wonyoung #naoirei #jangwonyoung
