IVE Part 1 — I Have Everything: The Origin Story
How six girls — including two IZ*ONE alumni — came together to form IVE, the girl group that debuted as if they'd been doing it for years. The casting stories, the meaning behind the name, and the debut that shocked everyone.
Most K-pop groups spend their first year proving they belong.
IVE spent their first week winning.
Seven days after their December 1, 2021 debut, they took their first music show trophy — the fastest a girl group had ever done it. Their debut song “Eleven” would go on to collect 13 music show wins total. Their fandom, DIVE, was forming before most people had even learned all six members’ names.
This wasn’t luck. It was design.
IVE was built — from the ground up — to arrive already complete.
📌 This is Part 1 of a 4-part IVE series.

🏢 Starship Entertainment: Five Years of Waiting
Starship Entertainment is not one of K-pop’s “Big Three” labels. But they’ve produced some of its most beloved acts — SISTAR, Monsta X, WJSN (Cosmic Girls), and Cravity among them.
After WJSN debuted in 2016, Starship didn’t launch another girl group for five years. That gap was deliberate. The company was watching how the 4th generation of K-pop was taking shape — what it needed, what was missing, and what kind of group they wanted to put into it.
Their answer was IVE: not a group that would grow into confidence, but one that would arrive already confident. Not rookies finding their footing — a finished product, fully formed.
To build that, they needed the right six people.
🎤 How Each Member Was Found
Six members. Five different paths. One vision: a girl group that debuts complete.
Yujin (An Yu-jin) — The Leader Who Was Already Famous, 2016
Yujin joined Starship as a trainee in 2016 at age 12. She was already known within the company for her performance instinct — sharp, natural, and unusually confident for her age.
In 2018, Starship entered her in Produce 48 — Mnet’s brutal survival show where Korean and Japanese trainees competed for spots in a temporary project group. Out of 96 competitors, Yujin finished 5th overall, earning a spot in IZ*ONE.
She spent two and a half years as IZ*ONE’s de facto leader — handling interviews, guiding younger members, representing the group with ease. When IZ*ONE disbanded in April 2021, Yujin returned to Starship not as a trainee waiting for a debut, but as a seasoned performer with a built-in fanbase and two years of group leadership behind her.
💡 Yujin became the MC of SBS Inkigayo in 2021 — hosting the very music show she would later win on as an IVE member. She’s known for her wit, warmth, and the kind of natural screen presence that can’t be trained.
Wonyoung (Jang Won-young) — The Center Who Arrived at 16, 2017
Wonyoung joined Starship in 2017. She was 13 years old.
In 2018, she entered Produce 48 alongside Yujin. She finished 1st overall — the center of IZ*ONE, the face of the group, the most visible K-pop trainee in Korea at age 14.
During IZ*ONE’s run, Wonyoung became one of the most recognized faces in Korean entertainment — not just in K-pop. Her visuals, her stage presence, and her composure at an age when most teenagers are still figuring out who they are made her something rare: a genuine cultural phenomenon before she was 18.
When IZ*ONE disbanded, the entire K-pop industry was watching to see where she would land.
She landed in IVE. As center. As if she’d never left.
💡 Wonyoung is one of the most commercially powerful members in 4th-gen K-pop — a brand ambassador for Miu Miu, Innisfree, and Samsung among others. In 2024, she won a 100 million KRW defamation lawsuit against a YouTuber who had spread false allegations about her.
Gaeul (Kim Gaeul) — Spotted at a Dance Competition, 2017
Gaeul didn’t audition through a conventional channel. She was scouted at a dance competition in Incheon in 2017 — a Starship representative saw her perform and reached out directly.
As the oldest member of IVE, Gaeul brings the group’s sharpest dance edge. Her movement is precise and controlled, with a cool detachment that reads as effortless on stage. She is widely considered the member with the strongest overall dance foundation — and the one who most consistently elevates IVE’s choreography in performance.
She’s quieter in variety show settings than some of her members, but on stage she is one of IVE’s most reliable anchors.
Rei (Naoi Rei) — One Voice That Stopped a Room, 2018
Rei is Japanese, born in Nagoya. In 2018, she passed the Loen Friends Global Audition in Japan — with the judges specifically noting her voice as the thing that made her stand out in the audition room.
She moved to Korea in May 2018, at age 14, speaking almost no Korean. She spent three years learning the language, training, and adjusting to life in Seoul — far from her family and the country she’d grown up in.
Rei is IVE’s main rapper, but her contribution to the group goes beyond her rap position. She has a playful, expressive personality that has made her one of DIVE’s most beloved members — and a fashion presence that has grown significantly since debut.
💡 Rei and Yujin went to the same school during their trainee years — a fact that became a warm detail for fans learning the group’s early dynamic.
Liz (Kim Jiwon) — Through the Open Door, 2019
Liz is from Jeju Island — the only member with roots in Korea’s southern island province. She joined Starship in 2019 through an open audition, the most traditional path of any IVE member.
She is IVE’s main vocalist. Her voice has a bright, clean tone that anchors the group’s sound in ways that aren’t always immediately obvious — Liz’s contribution tends to be felt more than noticed, which is the mark of a vocal line doing its job properly.
She has described her Jeju upbringing as grounding — a quieter, more nature-focused childhood than the Seoul-centric experiences of many of her members.
Leeseo (Lee Hyun-seo) — The Youngest, With the Longest History, 2019
Leeseo is IVE’s maknae (youngest member), born in February 2007. She joined Starship in 2019 at age 12.
Before Starship, she had already been working. As a child, she was an SM Entertainment Kids model — appearing in campaigns and developing performance instincts from an unusually early age. She had also been active in her school choir since third grade.
When IVE debuted in December 2021, Leeseo was 14 years old. She was the last member to be introduced in the pre-debut reveal sequence — and when fans saw her, the reaction was immediate. The group was complete.
💡 Leeseo’s energy is often described as the group’s spark — she’s the member most likely to say something unexpected, the one who makes the other five laugh without trying. In a group built on poise, Leeseo’s aliveness keeps IVE human.

🔗 The IZ*ONE Bridge: Why It Matters
Two of IVE’s six members — Yujin and Wonyoung — weren’t unknown quantities when IVE debuted. They were former members of IZ*ONE, one of the most successful project groups in K-pop history.
IZ*ONE (아이즈원) was formed through Produce 48 in 2018. The group ran for two and a half years — releasing four mini-albums, selling millions of copies, and building a passionate fanbase called WIZ*ONE. When the group disbanded on April 29, 2021, it was one of the most emotionally charged endings in recent K-pop memory.
For IVE, the IZ*ONE connection was both a gift and a challenge.
The gift: Wonyoung and Yujin brought experience, visibility, and a pre-existing fanbase that transferred its loyalty to IVE almost immediately. The group debuted with more industry credibility than any purely unknown lineup could have had.
The challenge: IVE had to be its own thing — not “IZ*ONE 2.0,” not a reunion vehicle, not a group defined by what two of its members used to be. They had to establish a new identity with six members who came from six different places.
They managed it — mostly because the music was strong enough from day one that the conversation shifted from “where are Wonyoung and Yujin now?” to “what is IVE going to do next?”
📛 What Does “IVE” Mean?
The name IVE is a shortened form of the phrase “I have” — a declaration of ownership over one’s own identity, talent, and presence.
The philosophy embedded in the name shaped everything about how the group was positioned: IVE doesn’t chase validation. IVE doesn’t need to prove anything. IVE already has it.
Their official greeting — “Dive into IVE, hello we are IVE” — reinforces the same energy: not “please like us,” but “come in, we’re ready for you.”
This was a deliberate distinction from many 4th-gen groups whose concepts centered on growth, struggle, or becoming. IVE started at the destination. The journey was about showing, not arriving.
🎬 The Debut: December 1, 2021
On December 1, 2021, IVE released Eleven — their debut single album.
The song is about the feeling of being someone’s entire world. Musically, it’s sleek and confident — not an aggressive debut, not a “look how hard we go” statement, but something polished and controlled that said: we know exactly what we’re doing.
It worked immediately.
- Debuted #1 on the Circle Album Chart
- Music show win within 7 days — fastest for a girl group at the time
- Went on to collect 13 music show wins with the debut song
- TikTok dance challenge spread globally within weeks
- Certified double platinum by KMCA
At the end of 2021 and into early 2022, IVE swept the Rookie of the Year awards at every major ceremony: Melon Music Awards, MAMA Awards, Golden Disc Awards, Hanteo Music Awards, and more.
But the bigger story wasn’t the rookie awards. It was what came next.
| Debut Date | December 1, 2021 |
| Debut Single | Eleven |
| Label | Starship Entertainment |
| Members | 6 (Gaeul, Yujin, Rei, Wonyoung, Liz, Leeseo) |

| Total Music Wins (Eleven) | 13 |
| Fandom Name | DIVE |

💭 Why “Already Complete” Was the Right Strategy
In a 4th-generation K-pop landscape crowded with groups debuting every month, differentiation is survival.
Many groups chose concepts built on rawness, growth, or “finding themselves” — concepts that invite audiences to invest in a journey. IVE took the opposite position: they arrived already defined. The concept was clarity itself.
This created a different kind of fan relationship. DIVE didn’t sign up to watch IVE grow. They signed up because IVE was already something worth watching. The group’s poise from day one — the way they carried themselves in interviews, on stage, in variety show appearances — communicated that this was not a group making it up as they went.
It was a bet that paid off faster than almost anyone expected.
