Juun

Juun (주은), born Kim Ju-eun (김주은) on December 3, 2008, is a South Korean idol and the main dancer and rapper of Hearts2Hearts (하츠투하츠) under SM Entertainment. Born in Ilsan, Goyang, Gyeonggi-do, she grew up in Icheon, Gyeonggi-do, coming from a military family. She has an older brother born in 2006. SM discovered her through dance videos posted online and reached out via Instagram DMs. At her first audition she performed Lee Hi's "Holo." She trained for four to five years, among the longer periods in the group. The family keeps a Toy Poodle named Haneul. Juun's path into K-pop was lit by watching BoA perform "ID; Peace B." She counts BoA and Red Velvet's Seulgi as her role models. Her MBTI is ISFJ, an evolution through earlier readings of ISTJ, INTJ, and ISFP. Her representative emoji is the alien (👾), chosen for her love of alien emojis. Within Hearts2Hearts, Juun calls herself the "Super Cutie" of the group. She is known for a husky voice, expert NPC character impersonations, and a deep love of Studio Ghibli. Juun debuted with Hearts2Hearts on February 24, 2025, with the single album The Chase. In October 2025, the group released their first mini album FOCUS. Her technical precision in dance and explosive stage presence have become defining traits of Hearts2Hearts live performances, making Juun the group's most kinetically expressive performer.
