QWER began in a way that was unusual even by Korean entertainment standards.
The four-member girl band was created through an online project led by creator Kim Gye-ran. Chodan, Magenta, and Hina already had audiences through streaming, YouTube, TikTok, and other online platforms, while vocalist Siyeon had previously been a member of the Japanese idol group NMB48.
What made QWER interesting was not simply that people who were already known online had been brought together to form a band. Much of the process of becoming that band was shown to the public from the beginning. Viewers saw the members practice, struggle with their instruments, make mistakes, perform, and gradually become more confident together.
I discovered QWER later rather than following them from their debut. A song first caught my attention, but once I went back and watched how the group had been formed, the story behind the music became almost as interesting to me as the music itself.
How QWER Began
QWER debuted on October 18, 2023, with the single album Harmony from Discord. The group consists of Chodan on drums, Magenta on bass, Hina on guitar and keyboards, and Siyeon as the main vocalist. Their debut date and first album are also documented through QWER’s official Weverse releases.
Their starting points were very different. Chodan, Magenta, and Hina already had their own online audiences, while Siyeon brought previous idol experience from Japan. Kim Gye-ran brought them together through the QWER Project, which documented not only the recruitment of the members but also their early training and daily life as the group took shape.
Even the name QWER reflects that background. Q, W, E, and R are familiar skill keys in games such as League of Legends, and each member became associated with one of the four letters. Gaming, streaming, anime, Japanese popular culture, and online communities were part of the group’s identity from the beginning.
At the same time, QWER was never simply four internet personalities left alone to figure out how to make a band. Professional production, management, training, songwriting, and music production were part of the project. What made the formation unusual was the combination of that professional structure with a process that remained unusually visible to viewers.
Growth Became Part of the QWER Story
Traditional idol training usually takes place before the public sees a group. Fans may know that a member practiced for years, but they normally meet that person after much of the awkward early development has already happened.
QWER exposed more of that process. The members did not all begin with the same amount of experience on their instruments, so viewers could compare early practice footage with performances months or years later. Learning was not simply something that happened before debut; it became part of the continuing story of the band.
Their backgrounds as online creators helped make that possible. They were already comfortable communicating through livestreams, casual videos, short clips, humor, and direct interaction with viewers. Practice sessions, mistakes, conversations, and ordinary moments could remain visible rather than disappearing once the official music career began.
The result was an unusual combination of creator culture and professional music production. A 2025 Weverse Magazine feature also focused heavily on QWER’s musical development and the members’ increasing participation in songwriting and composition as their live experience grew.
When the Music Started Carrying the Project
The formation story attracted attention, but QWER eventually needed songs that people wanted to hear even if they knew nothing about the YouTube project.
“T.B.H” (고민중독) became the major turning point in 2024. The song reached an audience far beyond people who had originally followed the individual members and became one of the songs most strongly associated with QWER. Weverse Magazine later noted that it ranked first among YouTube Korea’s most popular songs of 2024 and eventually passed 100 million streams on Melon.
Their sound also gave the band a recognizable identity. QWER often combines bright pop rock with melodies that can feel familiar to listeners of Japanese rock, pop, anime music, and game-related culture. That mixture fits naturally with the subculture influences already present in the group’s visual identity and formation project.
As the songs became more popular, QWER began appearing regularly at university festivals and larger live events. Those performances also brought more attention to the members’ actual playing because several of them had relatively short instrumental careers compared with musicians who had spent many years in bands before debut.
Questions about their musicianship and hand-syncing became part of the public discussion around QWER. But the band continued accumulating live experience rather than allowing that debate to define the project. By 2025, the members were also taking a more active role in writing and composing their own material.
In April 2026, QWER released their fourth mini album, CEREMONY, another sign of how far the project had moved from its experimental beginnings.
From Pentaport’s Global Stage to the Main Stage
Pentaport became one of the clearest places to see that development.
QWER first appeared at the Incheon Pentaport Rock Festival in 2024. Their inclusion drew criticism from some rock listeners who questioned whether a relatively new band created through an internet entertainment project belonged at an established rock festival.
In 2024, QWER performed on the festival’s Global Stage. Pentaport’s official final lineup lists them there alongside other artists performing on that stage. 2024 Pentaport final lineup
Around this period, cameras mounted near the members’ instruments also made their playing easier for audiences to see. The debates did not disappear immediately, but repeated live performances gave the members something that could not be produced by an argument online: more stage experience.

QWER returned to Pentaport in 2025. Siyeon later described that year’s performance on Weverse as taking place on the festival’s second stage, and the official Pentaport lineup confirms that QWER was again part of the festival.
Then, in 2026, QWER reached the Main Stage. Hina celebrated the performance on the group’s official Weverse account, writing that they had finally reached the Pentaport Main Stage on their third year at the festival.
For a group whose early videos invited viewers to watch them learn in public, the progression from the Global Stage in 2024, through another Pentaport appearance in 2025, to the Main Stage in 2026 gives that development a particularly visible shape.
The Song That Made Me Look Them Up
My own interest in QWER began with “Ferris Wheel” (대관람차).
I came across a video of the song in an online community I visit and clicked on it without knowing much about the group. The melody immediately appealed to me because it sounded bright while carrying a slightly nostalgic and wistful feeling underneath.
That was enough to make me look for more QWER songs. From there, I found the videos documenting how the members had been recruited and trained, and I ended up watching one episode after another.

What I enjoyed was seeing how different the early QWER looked from the group performing on later stages. The members were not presented as four musicians who had already mastered everything before the first episode. They practiced, looked nervous, made mistakes, improved, and became more comfortable with both their instruments and each other.
I am not part of QWER’s official fandom, Bawige, but they have become one of the Korean girl bands I enjoy following. “Ferris Wheel” was what made me curious about them, while watching their development was what made me interested in the group itself.
Why I Still Find QWER Interesting
By 2026, calling QWER simply a YouTube project band no longer describes what the group has become. They have released multiple albums, performed outside Korea, developed their own music further, and reached the Main Stage of one of Korea’s best-known rock festivals.
Their internet origins still matter because they shaped the way audiences first met them. QWER allowed people to see more of the unfinished stage of becoming a band than is normally visible in Korean popular music, while still working inside a professional production and management system.
They also remain difficult to fit neatly into one category. QWER belongs partly to K-pop, partly to pop rock, and partly to the worlds of internet creators, gaming, anime, and Japanese-influenced subculture that were built into the project from the beginning.
For me, though, the reason I still follow them is simpler. I remember finding “Ferris Wheel,” going backward through their earlier videos, and then watching their later performances with that beginning still in mind.
One of QWER’s songs is called “G9JB” (지구정복), which literally means “conquering the world.” I hope they keep going long enough to make that title feel a little less like a joke and a little more like a goal.
Until then, I’ll be cheering them on.
