Huh Yunjin (Korean: 허윤진; born October 8, 2001) is an American singer, songwriter, and producer based in South Korea.

[9] Huh later moved back to the United States and prepared to attend college, but abandoned her plans after Hybe Corporation contacted her in 2021 and offered her to debut with Le Sserafim, which she accepted.

[7] In 2018, Huh participated in the South Korean survival show Produce 48 by Mnet, representing Pledis Entertainment with After School member Lee Ga-eun.

[18] The self-written rock-influenced track features a trap beat with lyrics describing the judgment she faces as an idol based solely on her physical appearance.

[19][18] The title refers to both the words "idol" and "doll",[18] and the accompanying music video an animated character illustrated by Huh "navigating the attention and criticism she receives".

"[21] Divyansha Dongre of Rolling Stone India called the song "a sharp critique of the complexities of constantly living in the spotlight and the judgment that follows".

[23] Accompanying the indie pop single was a music video by South Korean animator and artist Ramdaram, which depicts a fan inspired by an idol to take better care of herself and learn songwriting before eventually fulfilling her own dream to perform on stage.
