YH’s page doesn’t list positions or roles, so we haven’t added them. Fan sites list such details, but we only use what the company publishes.

The company behind them

YH Entertainment’s music roster lists four acts: YENA, TEMPEST, DáFF and AND2BLE. YH: Music artists The company also manages actors.

YH sums up its mission with a slogan that appears across its website: “YOUR HOPE, HERE UNFOLDS.” In its own introduction, YH says it works alongside artists, fans and brands so that “hope” becomes real through concrete action and experience, and that it will grow together with them “until the moment everyone’s hope comes true.” About YH

The sequence story

YH’s album pages explain the idea behind the numbering. Sequence 01: Curiosity is about curiosity as the first instinct people have from birth. YH calls the album “the prologue to the journey AND2BLE will unfold.” It was built around three keywords: attraction, gaze and fear. YH: Sequence 01: Curiosity

Sequence 02: Attraction picks up where the first left off. In YH’s words, it captures “the emotional shift in which the ‘curiosity’ that began with the previous release grows into ‘interest’ in something specific and finally leads into a natural sense of ‘attraction.’” YH: Sequence 02: Attraction

Both albums came in three versions, and each version is named for a different angle on the theme:

Before the debut, the channel also posted RE:SENSE - Curiosity, a two-minute video, on April 25 (KST).

Our take: Calling releases “sequences” suggests a story told in parts. It’s worth listening to the two in order, since the titles say the second grows out of the first.

Two releases, in order

Sequence 01: Curiosity (May 26, 2026)

Five tracks: Curious, Aura, Sugar Rush, Bed and Happy &. Curious is the title track. YH: Sequence 01: Curiosity

The dance practice for Curious followed on May 31 (KST), so you can see the full choreography without camera cuts.

Our album guide goes through all five songs: Sequence 01: Curiosity.

On music shows

The broadcasters’ own channels have the early stages. Mnet aired Curious on M COUNTDOWN on May 28, along with a short debut interview, and MBC aired it on Show! Music Core on May 30. By June 11, the group was performing Aura on M COUNTDOWN as well.

Welcome to Qurious: the show concerts

AND2BLE’s show concerts are called Welcome to Qurious. The official channel posted stages from the Seoul shows in June and from Macau in July. Each member had a solo spot, and those solo videos are the ones on the member cards above:

• Seoul: ZHANG HAO sang TXT’s Good Boy Gone Bad, RICKY sang CHUNG HA’s 벌써 12시, and KIM GYUVIN sang WHO, first released by ASTRO’s Moonbin & Sanha.
• Macau: ZHANG HAO sang Why So Lonely, YOO SEUNGEON sang Know Me Too Well, and HAN YUJIN sang UP.

The group stages included NewJeans’ Ditto in Seoul and 恋人 (Lover) in Macau.

Sequence 02: Attraction (October 27, 2026)

Five tracks: Haunted, French Kissing, Potion, Beautiful and Worth It. French Kissing is the title track, and its video went up at 5:59 p.m. KST on release day. YH: Sequence 02: Attraction

Our album guide covers the five songs and the release week: Sequence 02: Attraction.

Official videos by release

All videos below are on the official AND2BLE YouTube channel unless noted. Dates are upload dates in Korea time.

Four things to notice

1. The show concerts were full of covers. At Welcome to Qurious, the members sang songs by other artists, in Korean and in Chinese. The group took on NewJeans’ Ditto in Seoul.

2. Two languages on one channel. ZHANG HAO’s cover of 一個人想著一個人 is a Mandarin song, and the Macau show included 恋人 (Lover), originally by Ronghao Li. Video titles give each member’s name in English and Korean.

3. A song got a second life. Happy &, the last track on the debut album, got its own special video on August 11, about two and a half months after release.

4. The b-side got its own practice video. Besides the title track, the channel posted a dance practice for Aura, the second song on the debut album, on June 8. It’s listed in the video table above.

Three ways to start

• Five minutes: watch the Curious MV, then the French Kissing MV. That’s the two title tracks, in order.
• Half an hour: play both albums from the first track. Each has five songs, and together they run about 31 minutes.
• An evening: start with Prologue, then watch the Sequence 02 fan showcase, which runs just over an hour.
