An Introduction to LOOΠΔ!

Hello humans! I decided to write this because far too few people know and appreciate Loona, so here is a guide! This will have guides to members, subunits, and the group as a whole, as well as links to every song released by the group as of now (March 2019)



Loona (LOOΠΔ when stylized) is a South Korean girl group under the entertainment company Blockberry Creative. Their Korean name, 이달의 소녀 (pronounced “Idarui Sonyeo”), translates to “Girl of the Month.” Their fans are called Orbits. The Loona pre-debut project introduced each member separately each month (hence the name), with breaks for sub-unit promotions. The pre-debut project started with Heejin’s debut on October 4, 2016, and finally ended on August 20, 2019, with the release of their official debut, Hi High. Loona has an overarching story (known as the Loonaverse) throughout all of their music videos that I will talk about in the last part, but I won’t get very deep into it because there are so many details and theories surrounding this storyline. I will mention their representative colors, animals, and in some cases fruits in the profiles and at the end.

The first part of this guide with cover members (listed below), the second part sub-units, and the third part Loona as a whole.

LOONA Discusses Their Strengths, Role Models, And 1st ...







Kim Lip





Go Won

Olivia Hye


I used information I already know for most of this, but for some of the fun facts and fact checking I used this source as well as the official Loona Instagram and Youtube accounts



Heejin was the first member of Loona to be revealed. Her first teaser image was posted to the official Loona Instagram on August 31, 2016. Her solo song, Vivid, was released on October 4, 2016, making her the first October girl. Her song is very upbeat and happy, matching her personality.

Stage Name: Heejin

Color: Hot Pink

Animal: Rabbit

Solo Song: Vivid

Solo B-side: Vivid (Acoustic Ver.)

Sub-unit: Loona 1/3

Fun Facts:

-She is one of the only three members (along with Hyunjin and Haseul) to have a 100% real live

-She can play guitar

-She is the only Loona member to have appeared in commercials (as of now)

-She speaks fluent Japanese

-She is afraid of Pigeons


Hyunjin was the second member of Loona to be revealed. The first “who’s next girl?” teaser came out on October 23, 2016. Hyunjin’s first teaser image was released on October 27, 2019, and the music video for Around You came out on November 16, 2019. Hyunjin was the first November girl. Her solo song, Around You, is very different from Vivid-instead of having a very bright, upbeat, and colorful concept, her song is slow and calm. Her light, airy voice shows through a lot with the song, as the instrumental is very simple.

Haseul was the third member of Loona to be revealed. Her “Who’s Next Girl?” teaser came out on November 30, 2016, and her first teaser image was released on December 7, 2016. The Let Me In video was released on December 14, 2016, meaning she was the first December girl and the last girl to be released in 2016. Her song was, again, a departure from Loona’s previous discography, drawing on her background in opera and classical music.

Her first teaser image was revealed on January 3, 2017, and Kiss Later was released on January 15, 2017. She was the first January girl and the first 2017 girl. Her song is very cutesy and the lyrics talk about the important topic of consent-she was only 15 when her song came out, and her song lyrics say “hug now/kiss later.” She is the only member who isn’t in a sub-unit.

Full Name: Im YeojinYeoJin (여진) | LOOΠΔ |

Vivi was Loona’s fifth member. While she is technically the first April girl (“Who’s Next Girl?” teaser on March 31, 2017, first teaser image on April 4, 2017, and Everyday I Love You release on April 16, 2017,) she was revealed first as a member of her sub-unit, Loona 1/3. Her song is, again, a newer style for Loona, this time with a 90s themed music video. Her music is happy but still fairly laid-back.

Kim Lip

Kim Lip was the sixth Loona member to be revealed. Her “Who’s Next Girl?” teaser was released on May 11, 2017, with her first photo teaser coming on May 14. The music video for Eclipse was released May 22, 2017, making Kim Lip the May girl. Eclipse showed a much different style of Loona-as well as covering a new musical style like Loona’s other releases, the song had a much more mature concept.

-according to Haseul, she is Loona’s girl crush member

-she wore a rainbow shirt that says “Love Will Win” in one of her photoshoots


Jinsoul is Loona’s seventh member. Many fans expected her to be released in place of Kim Lip because she appeared as a rapper in the song and music video for Vivi’s b-side, Everyday I Need You. Her “Who’s Next Girl?” teaser was released on June 7, 2017. Her first teaser image was released on June 12, 2017, and the music video for Singing in the Rain came out on June 25, 2017, making her Loona’s June girl. Her song was, like Kim Lip’s, a much darker concept than Loona 1/3 or their solos.

Choerry was the eighth member of Loona to be revealed. Her “Who’s Next Girl?” teaser came out on July 4, 2017, and her first image teaser came out on July 11, 2017. She is the July girl, as Love Cherry Motion came out on July 27, 2017. While Love Cherry Motion is a much cuter song then those of her Odd Eye Circle counterparts, there is a part that connects it to their more mature concepts (although I won’t spoil that for anyone because Love Cherry Motion shouldn’t be spoiled.)

With the release of New on November 27, 2017, she became the second November girl (after Hyunjin.) Her solo song, New, showed a new side of Loona, like the other solos before her.

Chuu was the tenth member of Loona. With her “Who’s Next Girl?” teaser on December 6, 2017 (my birthday!), her first teaser image on December 13, and the release of Heart Attack on December 27, she became the second December girl (after Haseul.) Her song is cutesy but powerful and very difficult vocally. Her music video was also widely recognized for its support of the LGBTQ+ community, stating in the description that Chuu (in the Loonaverse at least) is in love with Yves and portraying her as having a romantic crush on the other girl.

She was the second January girl following Yeojin. One and Only was, of course, a new sound for Loona, showcasing a unique style and a 3d audio effect on the youtube video.

Olivia’s first teaser image was released on March 16, 2019, and the music video for Egoist came out on March 29, 2018. Olivia is the March girl. Egoist presented possibly the darkest image of any Loona member, showcasing Olivia’s deep voice and dance talent.

That’s it for the members! This is already 2134 words and I’m not going to make it much longer, the sub-units and full group information will be in separate posts later on


Also, tell me if you want more of these profiles! They won’t be as long, because most groups aren’t as big or as complex as Loona, but I’d like to make more!

  1. Hi, Nora!

    My name is Karen and I’m a guest commenter. I’m a teacher from New Jersey. and I knew NOTHING about Loona until I read your post!! It is so thorough, with wonderful images and embedded videos!!

    How did you come across this band and fall in love with them? You obviously know a lot about them. What made you want to write a post about them?


    1. Hello! Thank you for commenting 🙂

      I came across this band from a random youtube video that was recommended to me, which was a guide to the members. I looked up Vivid and loved it, which got me into the rest of the group. I might do a post on this in the future, but I have a lot more things I want to do and there really isn’t that much to tell about it. I’m definitely going to finish my little guide to Loona series first, I still have to do the last part!

      Nora 🙂

  2. Nora,

    Well I think you have a real talent as a music reviewer! I also looked at your other post about another female band, and I watched the video. It was really good! Keep sharing!


    1. thank you! 🙂

  3. Hi Nora,

    I’m Kim and a guest commenter from Melbourne, Australia.

    You have put a large amount of effort and research you into this blog post! Adding photos and embedding videos gives your readers an added insight into each member of Loona. Do you have a favourite singer in the band? Or perhaps a favourite song?

    I didn’t know anything about Loona until I read your post! I hope you find time to continue with your follow-up posts.

    Keep up your fabulous blogging…

    Kim 🙂

    1. Thank you for commenting! I did spend a lot of time on this post, I’m glad you like it! I actually already finished my follow-up posts, you can find them on my blog if you want to see them 🙂

      My favorite Loona member is Olivia Hye, but I love all of them! My favorite song is really hard to pick because I love all of them, but my favorite solo is Egoist, my favorite sub-unit song (and fav overall) is Rendevous 18.6y, and my favorite full group song is either Where You At or Butterfly, they’re a bit too different for me to chose between.

      Thanks again!


  4. Hi I am Rafael, this is a very nice post. I am interested in this type of music now. Do you listen to other music made by different groups? Here is my blog:

    1. Hi! Thanks for commenting 🙂

      I do listen to a lot of other music! You can find some of the other groups I listen to in my monthly review stuff (February and March) and in my favorite music post (here) although that was an earlier post so it isn’t quite as good or detailed. If you don’t wanna do that, some of the other groups I listen to the most are Dreamcatcher, Oh My Girl, IZ*ONE, and CLC, so if you search any of those with mv behind it in Youtube it should take you to their songs! I’m glad you’re interested in Loona, I love their music and they all work so hard and are really good role models 🙂

      I’ll check out your blog!

        Korean pop groups work very very hard. Their labels schedule them for many TV show appearances, concerts, and so much stuff. In addition, those dances they do take a lot of practice and they have to perform them regularly. It’s one of the criticisms of the K-Pop scene that they have to work too hard when under contract.

    Nice job with the detailed information about this girl group. I lived in South Korea for 2.5 years. Loona was not around back then. Girls Generation was very popular. One thing I never understood was the huge groups. Have you ever felt like the number of members was a distraction for you? If you heard one of them sing, could you tell just by listening, which member it was?

    1. Hello! Thanks for your comment 🙂

      I honestly am not bothered by the number of members, especially in Loona because they’re all able to shine with their solos and sub-units. I can’t pick out all of their voices, but that’s just because I’ve never been very good at telling who is singing in a group just by their voice. I can pick out a lot of them, though, especially the members with voices that stand out more like Go Won and Olivia Hye. The only problem with bigger groups is that some members don’t get to sing very often but with Loona, again, this is pretty much remedied by their solos and sub-units and the fact that different members are pushed in different full group releases depending on the concept. I think there can be problems with big groups (for instance, Nako and Hitomi of Iz*one only got 4.5% each of their latest song, while Yuri got 15.4%, and Iz*one is another 12 member group), but Blockberry Creative (Loona’s Company) has done a very good job letting each girl shine.

      Nora 🙂
