The moment one member gets a solo album, the whole group’s internal physics quietly rearranges. Nobody says so out loud. The fans track it anyway.
On November 12, 2018, just over two years after BLACKPINK’s debut, Jennie released a song called “SOLO.” It was, in the most literal sense possible, a statement. The other three members of BLACKPINK would not release their own solo material for another two to four years. Jisoo, the last to go solo, didn’t release anything under her own name until March 2023 — more than four years after Jennie, and nearly seven years after the group’s debut.
Nobody at YG Entertainment ever stood up and announced a hierarchy. No press release explained why one member of a four-person group got to be an individual artist for half a decade while the others waited. The hierarchy existed anyway, and every fan of the group could have told you exactly what it was, because they had been tracking it the entire time.
Chapter One
The Order of Operations
K-pop groups do not formally rank their members. They don’t have to. The order in which solo activities are released does the ranking for them, and everyone in the fandom knows how to read it.
This is not a coincidence of scheduling. Solo release order in K-pop functions as a publicly legible signal of how a label ranks its own talent — who the company believes has the commercial pull to succeed independently, and in what sequence the company is willing to risk finding out. The member who debuts solo first is, structurally, being told: we believe in you enough to bet on you alone, before we’ve tested anyone else.
TWICE offers an even cleaner version of the same pattern, because JYP Entertainment ran it with near-mathematical consistency. Nayeon — the group’s oldest member and one of its most camera-forward visuals — went first in 2022. Jihyo, the leader, followed in 2023. Tzuyu, despite being one of the most recognized faces in the group internationally and a TC Candler “most beautiful” honoree, went third, in September 2024 — eight years after debut, and only after both Nayeon and Jihyo had already established a track record.
KpopWave Editorial
The order matters because it cannot be walked back. Once Jennie released “SOLO” in 2018, BLACKPINK’s internal hierarchy had a data point that didn’t exist before. Every subsequent solo release was read, by fans and industry observers alike, against that first signal — not in isolation, but as confirmation or contradiction of it.
Chapter Two
The Center Is Not Just a Position
If solo order is the long-term signal, the center position is the weekly one. In K-pop choreography, the center is the member positioned in the middle of the formation during the most visually prominent parts of a performance — usually the chorus, usually the part of the music video that becomes the thumbnail. It is, functionally, a company’s real-time bet on who the audience should be looking at.
NMIXX’s case in 2022 demonstrated how sensitive this signal is, and how closely fans monitor it. Weeks into the group’s debut promotion, JYP Entertainment shifted Sullyoon — already singled out pre-debut for visuals frequently compared to TWICE’s Sana and Tzuyu — into the group’s center position. The change wasn’t formally announced. Fans simply noticed it, in real time, comparing stage formations from one broadcast to the next, and the online discourse that followed split cleanly: some welcomed the change as a visual upgrade, others saw it as confirmation that “center” tracks “company favorite” more than it tracks “most talented.”
Line distribution: Stopwatch-precision counts of who sings how many seconds in a title track. Spreadsheets comparing distribution across an entire discography are a fandom genre unto themselves.
Center time: What percentage of a music video’s screen time, particularly during the chorus, is spent on each member in center formation.
Variety show appearances: Who gets booked for off-group content — talk shows, MCing gigs, brand campaigns — and how often, tracked as a proxy for company investment outside music.
Solo project cadence: Not just who goes first, but how much time elapses between each member’s individual release, and whether that gap is shrinking or widening over a group’s career.
Korean songwriting duo Cosmic Sound and Cosmic Girl, who have written for groups including MAMAMOO and ONEUS, addressed this directly in a 2020 interview: line distribution, they said, is determined primarily by which member’s vocal tone fits a given part of a song — not personal favoritism. This is very likely true at the songwriting level. It is also, from a fan’s perspective, almost entirely beside the point. Whether or not any individual decision is “fair” in isolation, the cumulative pattern across years of releases produces a hierarchy that is impossible to misread. Intent doesn’t change the math. The spreadsheet doesn’t care why.
Chapter Three
When the Group Has to Renegotiate Itself
The most interesting moment in this entire dynamic isn’t the solo release. It’s what happens when the group reassembles afterward.
A solo project gives a member something the group format structurally cannot: a complete, unshared frame. For the weeks or months that a solo era runs, that member is not one-fourth or one-ninth of a visual unit. They are the entire unit. They get final say — within company limits — over their own aesthetic, their own narrative, their own creative direction. BLACKPINK’s members were unusually direct about this in press interviews following their 2023–2025 solo run. Rosé described BLACKPINK as something close to an alter ego she’d been performing; her solo work, she said, let her “portray what I live and breathe.” Jennie spoke of having had “time with myself” to “dig deep inside of who I am.” Lisa, in a separate interview, said of her solo persona: “Everything, it’s just me.”

That language — “who I am,” “it’s just me” — is not incidental. It is a direct, if implicit, contrast with the group identity, which by definition requires compromise: shared lines, shared concepts, shared screen time, a single collective creative vision negotiated among several people and one company. A solo era lets a member test, publicly, who they are when none of that negotiation is required.
Then the group reconvenes, and the negotiation has to happen all over again — except now it’s happening with a member who has just spent months as the sole subject of millions of people’s attention, and who has, in some cases, built an entirely separate business infrastructure to support that. Returning to a four-way or seven-way or nine-way split of creative real estate, after months of having the whole frame to yourself, is not nothing. It requires an adjustment that group dynamics rarely discuss in public, and that fans, watching for it, almost always notice before the members say a word.
I don’t think fans who track line distributions and center positions with spreadsheet-level precision are being petty, even though that’s the easy dismissal. I think they’ve correctly identified that K-pop groups run on an economy of attention that is genuinely scarce and genuinely allocated — by someone, according to some logic, whether that logic is ever stated publicly or not. Tracking it is just a way of trying to see the machine that everyone agrees is operating but that nobody in charge of it will describe.
What I find more interesting than the tracking itself is what it reveals about how little K-pop has actually resolved the tension between the group as a collective artistic unit and the group as a collection of individually marketable people. BLACKPINK’s solution — four years of staggered solos, followed by four separate solo agencies operating alongside one shared group contract — is a genuinely clever piece of structural engineering. It lets each member be fully themselves on their own time, and fully BLACKPINK on the group’s time, without forcing either mode to compromise the other.
But it took until 2023 — seven years into the group’s existence — for that structure to fully exist. For most of BLACKPINK’s career, and for the entire careers of most other groups operating right now, the solo question doesn’t have a clean structural answer. It just has an order. Someone goes first. Someone goes last. And everyone, including the members themselves, is left to read the sequence for what it says about where they actually stand — because nobody is going to come out and tell them directly.
The center position rotates every comeback. The solo release order never does. That’s the one nobody gets to renegotiate.
