Thirteen, and on stage.

A new girl group tops the chart in 29 hours. Then the questions start.

The cheers did not last long. Within a week, photos of a 13-year-old member in a crop top and short shorts were all over Korean websites. Many people called the album cover inappropriate.

The group comes from Lee Soo-man, the man who built SM Entertainment, one of Korea’s biggest music agencies. He launched BoA at 13, back in 2000. He knows this road well.

Your thoughts?

At 13, what were you doing on a Monday night? Could you have stood on that stage?

Thirteen isn’t new02 / 08

Thirteen isn’t new.

K-pop has put young teenagers on stage for 26 years. Girls and boys alike.

Lee Soo-man found BoA at 11, when she came along to her brother’s audition. In an old video that went viral again this month, he shares his formula: debut at 13 to 15, and you peak at 16 to 18.

Taiwan has its own story. In 2012, scouts spotted a 13-year-old girl at a performing-arts school in Tainan. Three years later, Tzuyu debuted with TWICE.

An idol’s best years are short. Starting early “buys them more of that time.”Jung Duk-hyun, culture critic

Your thoughts?

More years at the top, in exchange for a childhood on stage. Is that a fair trade at 13?

Before the lights: long days, small meals, and a door marked “too old” at 20.

The 16 former trainees described strict diets, fainting, loneliness, and trouble keeping up at school. One said of the youngest girls: Because they are young, they do not fully understand how serious it is when their period stops.

And the clock runs fast. “Once they pass 20,” an industry insider told The Korea Times, “many start feeling they are considered too old.”

Your thoughts?

EJAE never debuted, then won a Grammy. Does the trainee system find talent, or waste it?

Each dot is one member, by age at debut in October 2026 (birth dates from fan profile sites). Girl trainees slightly outnumber boys too, but not by much.

The age gap is small. The difference is in how the children are presented.

This month’s complaints were about the girls’ outfits, not the boys’. And in 2025, a TV audition show called Under 15 put 59 girls aged 15 and under in heavy makeup and showed their photos with bar codes. Critics said it made them look like products.

After a public outcry, it was canceled three days before its first episode.

Your thoughts?

Boys and girls start at about the same age. So why do the girls get most of the attention, and most of the criticism?

The fans05 / 08

Who’s really watching?

The old rule: boy groups for girls, girl groups for men. Only half of it holds.

Album buyers at the Korean online bookstore Aladin (2022) and for one NewJeans album (KBS Joy, 2023); listeners on the music app Genie (2022). Women were the majority for 17 of the 27 girl groups Aladin checked.

Men haven’t disappeared. Koreans even have a word for grown men who follow girl groups: samchon fan, or “uncle fan.” But in 2022 a Seoul newspaper reported that the old rule, girl groups for male fans, no longer held. Many girl groups now sell an image young women want to copy.

Your thoughts?

If most of the buyers are young women, then who is a 13-year-old’s crop top for?

Same top, different stage06 / 08

Same top, different stage.

American girls wear crop tops too. What changes is who chooses, and for whom.

In a viral TikTok, an Iowa mother filmed the girls’ section of a Target store, full of short tops. It shouldn’t be this hard, she said, to find a full-length shirt for her 6-year-old. American parents split. One let her daughter start at 10 and saw nothing sexual in it, unless adults bring it. Another made a deal: a tank top underneath as a tween, a little skin at 14.

Sexualization, said an American Psychological Association report in 2007, includes sexuality imposed on a girl, rather than chosen by her.

Comfort counts too

Dancing under stage lights is hot work. A fitness guide tells people exercising in the heat to wear “minimal clothing,” or light, loose clothes. Street dancers do both: tank tops or baggy tees.

Sometimes, they choose

In July 2025, some fans said IVE’s outfits at an outdoor football match were too revealing. Member Rei said the members had asked for their uniforms to be remade the way each of them wanted.

Your thoughts?

Comfort, choice or image: how much of a stage outfit is each? If comfort were the only reason, would boys and girls dress the same?

Two clocks07 / 08

Two clocks.

Same debut age, different shelf life.

All 1,182 idol groups that debuted from 1996 to 2025. Nearly half are gone within three years; by the time a standard contract ends, about one in four is left.

Why do boy groups last longer? Professor Kim Jeong-seop, who studied all 1,182 groups, says boy groups build loyal fans who buy albums, tickets and goods again and again. Girl groups depend more on general popularity: streaming and events.

A faster clock may also explain the rush. The younger the debut, the more years before people call an idol “too old.”

Your thoughts?

Why might boy-group fans stay loyal for longer? Are fans of girl groups different, or treated differently?

The rules08 / 08

The rules.

Korea has a law. Critics say it has holes. Taiwan’s is stricter, on paper.

The limits cover work: shows and recordings in Korea, a real job in Taiwan. Training doesn’t count, so a trainee’s day can run right up to the line, or past it.

One square = one hour. Taiwan also caps the day at 8 hours.

South Korea

  • Under 15: no more than 35 hours a week, and no work from 10 p.m. to 6 a.m. (until midnight before a school holiday, with consent)
  • Ages 15 to 18: up to 40 hours a week
  • Since Aug. 2025: agencies may not force minors to skip school, show “excessive exposure,” or manage their looks to extremes
  • Every agency needs a youth protection officer

Taiwan

  • Under 15: employers can’t hire you without government approval
  • Age 15: at most 8 hours a day and 40 a week
  • No work from 8 p.m. to 6 a.m., and none on rest days
  • The catch: these rules protect a child only if the child counts as a worker
The holes critics point to
  • No direct penalty for breaking the hour limits
  • The limits cover broadcasts and recordings, not the years of training
  • Courts usually don’t treat idols as “employees,” so the main labor law doesn’t apply
  • No minimum age for a debut, and no one defines “excessive”

What England does

A child performer needs a license from the local council first.

A lawyer’s view

Little has changed since 2025, says lawyer Kim Doo-na, and some agencies don’t seem to know the new rules.

Your thoughts?

Should there be a minimum age for a debut? If so, what age, and who should check?

Before you goLENS · 01

Things to ponder.

Over a cup of tea, on your own or with someone who disagrees.

  1. A talented 12-year-old in your family wants to train in Seoul. What would you say? What rules would you set?

  2. Fans buy the albums and the streams. Do they share some responsibility for how young idols are treated?

  3. Lee Soo-man says he “will handle it well.” What would handling it well look like to you?

  4. Taiwan’s labor rules are stricter on paper. Should Taiwan want its own idol industry, under rules like these?

  5. Boys and girls debut at the same age, yet the debate keeps landing on girls’ bodies and clothes. Where else do you see that happen?

  6. What would you tell your 13-year-old self about fame?
