Trainee Days

Hee-jin was born as Jeon Hee Jin on October 19th, 2000, in Bundang District, Seongnam, Gyeonggi Province, South Korea. She is the youngest of three daughters in her family. Hee-jin realized that she wants to become a singer when she was in middle school. At one time, she shared similar dreams with both of her sisters, 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 four hours of distance in order to attend a dance academy. Her father began discouraging her dreams of becoming a singer after she was rejected at 20 different auditions.

However, in 2015, she was cast through social media by BlockBerry Creative and became a trainee. Hee-jin trained for one year before she was selected to be the first member of the agency’s upcoming girl group, LOOΠΔ.

Pre-debut Story

On September 25th, 2016, a video teaser titled “LOONA’s 1st Member ‘HeeJin’ SeoulTeaser” was released on YouTube featuring promotional posters of Hee-jin in the streets of Seoul. Hee-jin is the only member to not have a “Who’s Next Girl?” teaser image because she is the first member and hence it was not necessary.

On October 2nd, 2016, BlockBerry Creative released a video teaser titled “Paris” to tease the acoustic mix of ViViD featuring Hee-jin while filming in Paris.

She debuted on September 26th, 2016, as a member of the girl group LOOΠΔ and subsequently released her solo single album Hee-jin on October 5th, 2016.

She was later revealed to be a member of its first subunit, LOOΠΔ 1/3.

Hee-jin was also featured in Olivia Hye and Go Won‘s duet, “Rosy,” where she also covered the rap part of the song.
