2000-2018: Early life and career beginnings

HeeJin was born as Jeon Heejin on October 19, 2000 in Bundang-gu, Seongnam, Gyeonggi Province, South Korea. She is the youngest of three daughters in her family. HeeJin's decision to become a singer occurred in middle school. At one time, both her sisters had similar dreams to hers, but they remained unfulfilled. She has stated that one of the reasons she became a singer was to make her sisters’ unfulfilled dreams come true and has cited her sisters as being her biggest supporters. For this, she traveled long distances in order to attend a dance academy. Her father began discouraging her dreams of becoming a singer after she was rejected at several auditions. However in 2015, she was casted through social media by BlockBerryCreative and became a trainee. HeeJin trained for 1 year before she was selected to be the first member of the agency's upcoming girl group.[2]

On September 26, 2016, HeeJin was revealed as the first member of girl group LOONA, and released her pre-debut single on October 5, 2016.

In October 2017, HeeJin, along with fellow LOONA members HyunJin and HaSeul, auditioned for survival reality show MIXNINE. Having passed the audition, she became a contestant as a representative of her agency and idol group.[3] HeeJin made it until the final episode, but was eliminated when the boys' team won against the girls', and hence ultimately did not get to debut.[4]
