She debuted on September 26, 2016 as a member and subsequently released her solo single album HeeJin on October 5, 2016.
Early life (2000–2016)
HeeJin was born as Jeon Hee-jin on October 19, 2000 in Daejeon, South Korea. She is the youngest of three daughters in her family. She attended Incheon Hambak Elementary School and Saint Paul Girls’ Middle School in Chungnam, South Korea. At some point during her childhood, she lived for one month in Brazil.
HeeJin first wanted to become a singer when she was in middle school. At one time, both her sisters had similar dreams, but those dreams were ultimately unrealized. HeeJin 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.
In pursuit of her goals, HeeJin 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 20 different auditions. However, in 2015 she was cast through social media by BlockBerryCreative and became a trainee. HeeJin trained for one year before she was selected to be the first member of the agency’s upcoming girl group.
2016: Reveal, solo debut, “I’ll Be There”, “The Carol”
On September 25, 2016, a video teaser titled “LOONA’s 1st Member ‘HeeJin’ SeoulTeaser” was released on YouTube featuring promotional posters of HeeJin on the streets of Seoul.
On November 10, HeeJin had a cameo in the alternate version of the music video for HyunJin’s “Around You”. She additionally released a song with HyunJin titled “I'll Be There,” which was included on HyunJin’s debut single.
HeeJin is the only member to not have a “Who’s Next Girl?” teaser image; as she was the first member, such a teaser was unnecessary.
2017: “My Sunday”, commercial films, LOONA 1/3, “Singing in the Rain”, Woomanna, MIXNINE
HeeJin has had cameos and supporting roles in the highest number of solo music videos out of all members of LOONA. On April 17, HeeJin was included in member ViVi’s music video “Everyday I Love You”, alongside HyunJin, HaSeul, and YeoJin. On June 23, she was featured on a special version of JinSoul’s “Singing in the Rain” where she covered the rap portion of the song. On December 9, she appeared in HyunJin’s special music video “Around You - Woomanna Special Ver.” which featured scenes from the web drama Woomanna; HeeJin starred in first season and second seasons of Woomanna in main role.
In October, HeeJin, along with fellow LOONA members HyunJin and HaSeul, auditioned for the survival reality show MIXNINE. After passing the audition, she became a contestant as a representative of her agency and idol group. HeeJin made it until the final episode, but was eliminated when the boys’ team won against the girls’.
2018: AVAJAR, “Rosy”, LG QT/QT/ + TV, debut in LOONA
In March 2018, BlockBerry Creative announced HeeJin had signed an advertising model contract with Korean cosmetics brand AVAJAR. She advertised the company’s products along with Kyulkyung (formerly of PRISTIN) and Cheng Xiao of WJSN (Cosmic Girls). Shortly afterward, a commercial film featuring HeeJin along with HyunJin, Cheng Xiao, Kyulkyung, and members of Super Junior was released for the brand.
On March 7, HeeJin appeared on one episode of Woomanna’s third season, reprising her role from seasons 1 and 2.
2019: High school graduation, HI MART
On January 1, 2019, HeeJin starred in a commercial film for HI MART.
On January 7, HeeJin graduated from Hansung Girls’ High School alongside HyunJin.
On February 24, HeeJin appeared as a contestant on King of Masked Singer as "Enter Lady" against contestant "Play Guy". While singing Sunmi's "Full Moon (보름달)" she revealed herself, and later expressed her emotions through LOONA's instagram.
On April 18, HeeJin alongside Chuu and Yves appeared on JBTC's "Ask Us Anything". A clip of them dancing to their title track "So What" also on YouTube. Later on April 26, HeeJin starred as the main role in BEN's music video 'Bad'
