Meet K-Pop Girl Groups Originally Consisting of Seven Members!

Increasingly popular, the development of K-Pop every year is getting better, even now it is worldwide. Every year, there are always new boy groups and girl groups that debut with various concepts. Various agencies in South Korea are competing to name their superior trainees, and are working hard to make their boy/girl groups more popular.

The success of boy groups or girl groups that have debuted first and become very popular often becomes the standard for their agency to debut a group, including the number of members in a group. In this article, we will discuss girl groups from various agencies that originally consisted of 7 members.



Apink is a girl group that debuted in 2011, under CUBE Entertainment or now known as Play M Entertainment. Apink debuted with 7 members, Park Cho-rong, Yoon Bo-mi, Jung Eun-ji, Son Na-eun, Hong Yoo-kyung, Kim Nam-joo, and Oh Ha-young, they debuted on April 19th, 2011, with the release of their first extended play (EP), Seven Springs of Apink and the music video for its lead single, “Mollayo” (몰라요; “I Don’t Know”).

Since their debut, Apink has won awards at shows such as the Golden Disc Awards, the Seoul Music Awards and the Mnet Asian Music Awards. Their first music show appearance was on M Countdown on January 5th, 2012, for “My My” from their second EP Snow Pink. But unfortunately, in April 2013, Hong Yoo-kyung decided to leave the group to focus on her studies.


Apink’s image and music style are often compared to first-generation idol girl groups S.E.S. and Fin.K.L. Apink has an innocent and girlish image, unusual among girl groups’ sexy concepts. In 2012, member Oh Ha-young said, “Other girl groups these days tend to highlight their dancing skills and sexy looks, but our concept was an innocent and pure image. I think that’s why the audience feels comfortable with us.” Apink’s music generally fits within the bubblegum pop genre, with signature cheery lyrics.

With the release of their 2018 “I’m So Sick,” Apink showed a shift in their style of music, moving towards a more mature and sophisticated sound. The track, with its use of autotune, synth and house beats, and its lyrical content of having ‘not even one’ bit of feeling left for an ex, makes “I’m So Sick” a much bolder track than what Apink is known to put out. Their 2019 “%% (Eung Eung)” does much of the same. Its use of ‘Izzy synths, snapping beats and slapping percussion as the members sing about the type of person one should love’ make “%% (Eung Eung)” another song that is a departure from much of Apink’s earlier work. To date, Apink has released eight Korean mini-albums, three Korean studio albums, and three Japanese studio albums.

Last February, Apink finished their concert PINK WORLD 2020, which is their sixth concert. On January 9th, Apink’s agency, Play M Entertainment, officially announced, “Just five minutes after tickets went on sale for Apink’s solo concert Welcome to PINK WORLD, which will be held on February 1st and 2nd at Olympic Hall in Seoul’s Olympic Park, all seats for both concerts completely sold out.”

Notably, the upcoming concert marks the sixth consecutive time that Apink has managed to sell out a solo concert; the girl-group currently holds a perfect record starting from 2015, when they held their very first solo concert, Pink Paradise. Titled Welcome to PINK WORLD, Apink’s upcoming concert will feature a fun “festival” theme. According to Play M Entertainment, the members have personally contributed ideas and participated in the planning of the show. It is known that there are many celebrities who attend their concerts, including MAMAMOO’s Moonbyul, BTOB’s Ilhoon, actress Moon Ga-young, Park So-dam, and there’s also support from MAMAMOO’s Solar for Chorong.

The company announced that the group would return as a quartet consisting of Nari, Jiae, Woojoo, and Sujin, but made no statement about Dain and Jinju, which led to speculation that they had left as well.

This first studio album — Dystopia: The Tree of Language — was released on February 18th, together with the music video for “Scream,” an uptempo EDM song. Although this was the first promotion since the debut where the group performed as six members (Handong was not present due to an ongoing overseas commitment), the dance for “Scream” was nevertheless choreographed for seven members in order to enable full-member participation in the future. In total, the album features eight new original songs, packaged with Dreamcatcher’s previous two fan songs “Full Moon” and “Over The Sky,” as well as Siyeon’s solo debut song “Paradise.”

Although there is a change of members or the addition of members in a group is quite common, but this is not a benchmark that they are a group that fails or is not popular, only sometimes there are some members who prefer their own way, or with various health problems. And even though it might be difficult to accept at first, not a few groups can still get up and go through it all.

Let’s support and look forward to the activities of each group that still exists, in the future, and continue to give love to each member and hope they remain happy and healthy in the future as well!
