Stella

Stella (스텔라), born Kim Da-hyun (김다현) on June 18, 2007, in Ulsan, South Korea, is the Lead Vocalist of Hearts2Hearts under SM Entertainment. She carries the English name Stella Dahyun Kim. At four or five years old, Stella's family relocated to Vancouver, British Columbia, Canada, where she grew up bilingual in Korean and English. After returning to South Korea, the family settled in Busan, where she attended Doctor Music Academy. At an in-house showcase, she was scouted by 32 of 60 agencies in attendance. She trained for two years before debuting with Hearts2Hearts on February 24, 2025, with the single "The Chase." At 167 cm with an INFP personality, blood type O, and a left-handed grip, Stella is the kind of performer who appears reserved until fully comfortable, then fully lets loose. She plays guitar, drums, and piano. Her favourite colour is pink, her role model is Red Velvet's Wendy, and her representative emoji is a cupcake. She is housed with fellow member A-na in Dorm 1. Hearts2Hearts have released The Chase (February 2025), Butterflies (April 2025), Style (June 2025), the mini album Focus (October 2025), and the digital single RUDE! (February 2026). Stella appears across all releases as Lead Vocalist.
