Most groups introduce themselves with a concept. A2O MAY introduce themselves with a season. Their agency describes the five members as girls “blossoming like May flowers,” sent to announce the start of something it calls the Zalpha Generation. Since their debut in December 2024, they have released six songs, and the latest, BAD HABITS TONITE, came out on October 18, 2026.
This guide covers who they are, the company behind them, what “Zalpha” means, and the order to hear their songs in.
Who are A2O MAY?
A2O MAY are a five-member girl group from A2O Entertainment. The company’s official site introduces them in one line: “A2O MAY is a dynamic ensemble of five talented young girls blossoming like May flowers through their radiant beauty, announcing the birth of the Zalpha Generation.” A2O Entertainment official site
Their first official video, Under My Skin (A2O), went up on December 20, 2024, with a simple line in the description: “A2O MAY has officially debuted!”
A2O MAY were the first of A2O’s three groups. In October 2026 they were joined by a girl group, A2O LITE, and a boy group, A2O SOUL.
Meet the five members
The official site lists the members in this order. Their official video descriptions use the same names and order, from the debut to the latest single.

| MICHE |
| KAT |
The official site doesn’t give member positions, birthdays or nationalities yet, so we haven’t added them. Fan sites list some of these details, but we only use what the company publishes.
The company behind them
A2O is short for “Alpha to Omega.” According to the company, the name stands for fans and artists working together from the beginning of a project (Alpha) to its end (Omega). A2O Entertainment official site
The site lists three parts of the plan:
- A2O ROOKIES: finding and training new artists, using the experience of producer S.M. LEE, whom the site calls “a pioneer of the Korean idol industry.” The Korean and Japanese versions of the site give his full name: Lee Soo-man (이수만).
- CELEBRITY IP: building original IP based on A2O’s metaverse storyworld, through music projects, as a base for idol “celebrity IP.”
- PLAY2CREATE: letting fans and creators remake the company’s original content, and even earn from it, inside the A2O platform.
Zalpha joins Gen Z and Gen Alpha. The company calls its music Zalpha Pop, and it wants those two generations to do more than listen. It wants them to become “prosumers” who recreate and add to the content.
A2O MAY’s official videos on A2O WORLD carry the same three-line credit: “Zalpha Pop by A2O. Produced by S.M. LEE. Presented by A2O Entertainment.”
Our take: “Zalpha” sounds like marketing, and it is. But it also tells you who the songs are for: listeners who grew up making short videos, not just watching them.
Six releases, in order
The official site lists six releases for A2O MAY. Here they are from first to latest, with the date each official video went up:
| Release | Official video (KST) | What the video description says |
|---|---|---|
| Under My Skin | December 20, 2024 | “A2O MAY has officially debuted!” |
| BOSS | April 25, 2025 | Their 2nd digital single |
| B.B.B (Bigger Badder Better) | August 15, 2025 | Their 3rd digital single, featuring A2O LTG |
| PAPARAZZI ARRIVE | October 24, 2025 | — |
| Love Got Me Ooh | July 17, 2026 | Tagged as a comeback |
| BAD HABITS TONITE | October 18, 2026, 7 p.m. | Released at 6 a.m. EDT / 7 p.m. KST |

Watch the original on YouTube ↗Four things to notice
- Almost every single gets a dance video. A2O WORLD posted stage performance videos for Under My Skin, BOSS, B.B.B and PAPARAZZI ARRIVE. The A2O MAY channel added a practice-room version of Under My Skin.
- BOSS has a “Super Close-Up” version. A second official video for BOSS went up a week after the first. As the name says, it’s the close-up cut.
- PAPARAZZI ARRIVE was filmed with A2O’s own camera tech. Its performance videos are “Powered by Infinite Studio.” In 2026, A2O described Infinite Studio as its 4D Gaussian Splatting technology: “from a camera that captures, to a camera that creates.”
- BAD HABITS TONITE has a Chinese version. The A2O MAY channel posted it the day after release. The same channel has shared full stages of the song, including one from Jiangsu TV’s Music Show 2026.
Three ways to start
- If you have five minutes: watch Under My Skin, then BAD HABITS TONITE. That’s their first song and their latest, almost two years apart.
- If you have half an hour: play all six in order: Under My Skin, BOSS, B.B.B, PAPARAZZI ARRIVE, Love Got Me Ooh and BAD HABITS TONITE.
- If you love dance: skip the music videos and go straight to the stage performance videos, then the BOSS Super Close-Up.
Quick answers
Is it “A2O” or “A20”? It’s the letter O, from “Alpha to Omega.” A few video titles, even on A2O’s own channels, write it with a zero, but the company name uses the letter.
Who produces them? The video credits say “Produced by S.M. LEE.” The Korean and Japanese versions of A2O’s site name him as Lee Soo-man.
Who is A2O LTG? B.B.B is credited “feat. A2O LTG.” A2O hasn’t introduced LTG on its official site, so we haven’t guessed.
What don’t we know yet? Member positions, birthdays and official song descriptions. We’ll add them when A2O publishes them.
Where to go next
- The new girl group: A2O LITE, nine members and the debut single NEON, if you want A2O’s newest girls.
- The new boy group: A2O SOUL, fifteen members and SUPERSTAR, with a debut EP coming November 9.
