Hong Eunchae is the youngest member of LE SSERAFIM, the Source Music and HYBE girl group that debuted on May 2, 2022 with the mini album FEARLESS. She joined the group at 16 after years of dance academy training, and she is known for her sunny, upbeat personality and nicknames such as Smile Potato and Happy Virus. Beyond the group, she spent a stretch as an MC on Music Bank and hosted her own interview show, Eunchae's Star Diary. With her four bandmates she has played Coachella (2024), the VMAs (2024) and the Easy Crazy Hot tour across Asia and North America (2025).
Where they grew up
Eunchae was born in Seoul, in the Seongsu-dong area of Seongdong-gu, and has an older brother she video calls when they are close. She began dancing as a hobby in elementary school, learning choreography in after-school classes because K-pop was popular with her friends. The hobby grew into a dream, and at 12 she enrolled at DEF Dance Skool, a well-known Korean academy for aspiring singers and dancers. There she studied technique and filmed K-pop dance covers for the academy's YouTube channel, and dance became a way to put bad days behind her. Her skills drew the notice of HYBE through the 2021 Source Music auditions, which led to her debut with LE SSERAFIM. She has also said that the group Apink was her first favorite idol act, long before she thought of becoming an idol.
