HeeJin (Hangul : 희진; Japanese : ヒジン, Hijin) is the first member of the girl group LOONA.
She is the sixth youngest in LOONA, and the third youngest in LOONA 1/3. Revealed on September 26, 2016, she is also the only member to not have a "Who's the Next Girl?" teaser because she is the first member to be revealed. Her solo single album "HeeJin" was released on October 5, 2016.
In the group, she's represented by a rabbit and the color vivid pink. In LOONA 1/3, she is associated with the location “Paris, France”.
- Her nickname Heekki (희끼) is a portmanteau of her name and the word for rabbit (토끼). She originally gave this name to the rabbit she met on set while filming her first MV.
- It was later evolved to Muscular Bunny.
- Another nickname: "Jeon Hwi Hyeol"
- There’s a popular and apparently a bit cringy web-novel called < 세계 서열 0위 포커페이스 반휘혈 > and the main character’s name is 반휘혈 (Ban Hwi Hyeol) who’s the best fighter and coolest kid in his high school.
- Jeon Soo Jin (全素振), since she has adopted a partially vegan diet.
- In Hanja, Jeon can mean 田 (field) or 全 (all/fully), and both are common Korean surnames. The Hanja for "Vegan" is 全素.
- Vemimem (Vegan Crazy Member).
- HeeJin's eyebrows are naturally a pale gray color.
- She was voted as the best visual in MIXNINE.
- Lots of people first thought she wasn't fully Korean (visually speaking).
- When they first joined Yves and Go Won were pranked and were told by the staff that HeeJin's grand mother was Russian. Yves believed that lie for a week, because she thought Heejin's nose was attractive and not typically Korean.
- According to JinSoul, she also has fair skin.
- She thinks her charming points are her Danmuji-like eyebrows (thick eyebrows) and her penguin-like lips.
- She can play the guitar and piano.
- She's well known for her muscular arms. Despite this, she is the second-worst in the group in arm wrestling.
- HeeJin's role models are Lucia (Shim Kyusun) and Girls' Generation's Taeyeon.
- Her best LOONA friend is HyunJin.
- In turn, Chuu's best friend in terms of common interests in HeeJin.
- Age difference between her sisters and her: 5 years and 3 years. She's pretty casual with both sisters and doesn't have to use honorifics ("unnie") with them.
- Her family is currently (November 2020) raising 3 dogs: Nori, Tori and Bori. Bori is a puppy.
- She got Nori when she was 12 years old. She was getting ready for school one morning and suddenly she saw a puppy in her house. He was already really friendly. Her family got Tori when she was living in Seoul so she couldn't spend much time with Tori when it was a baby and felt disappointed about that.
- At one point, when she was about 9 years old, her family were raising 7 dogs (probably puppies) at the same time: Momi, Mingki, Jjinga, Ming-ie, Honga, Taengi, Toto.
- HeeJin is actually allergic to dogs but she loves her dogs so much she just takes allergy meds.
- Chuu considers her one of the closest friends and idol because she was already mesmerized by her looks when she saw her solo poster before Chuu made her debut.
