Could Itzy take the K-Pop crown from all the Blackpink members?

Behind-the-scenes access remains one of the most revealing windows into how K-pop groups build their sound and identity. ITZY offered that access with the two-part documentary that accompanied their 2023 mini-album Kill My Doubt. The footage captured training sessions, recording sessions, and the emotional weight that comes with turning personal experiences into music. The project also marked a turning point for the five members as they moved past their fourth anniversary and began mapping a longer career path.

The tea

Boxing classes, late-night vocal takes, and honest group conversations filled the documentary. The members described the process as physically and mentally demanding, yet the core message stayed consistent: facing doubt head-on. That theme first surfaced with Cheshire in 2022 and carried forward. Later releases kept the personal storytelling approach while expanding the sonic range, and the same documentary-style content appeared in subsequent promotions to keep fans connected to the creative process.

The depths

Yuna called the pre-album interviews psychological counseling because they gave each member space to name fears without judgment. Yeji framed the album as an exercise in confronting doubts before attempting anything new. The lead single Bet On Me opened with that internal dialogue and turned it into a group anthem. Lia noted the goal was relatability so listeners could recognize their own worries in the lyrics. Those 2023 conversations still serve as the foundation for how the group handles challenges during recording and touring, and the psychological approach has shaped later group dynamics.

The pallette

None of My Business arrived as a breezy, low-stakes track about moving on, and Chaeryeong immediately claimed it as the ideal sunset beach song. Cake, the title track, brought the group back to their signature bright energy while simplifying life’s problems to the act of enjoying dessert. That contrast between laid-back and high-impact tracks previewed the stylistic variety that showed up in later mini-albums, where the same mix of catchy, relatable anthems continued to define the sound.

World Tour Expansion

ITZY completed multiple world tours after Kill My Doubt. Their third world tour, Tunnel Vision, began in Seoul in February 2026 and extended through Asia, Oceania, and Europe. April 2026 brought the first full-member arena run in Australia and New Zealand, followed by additional dates in London, Amsterdam, and Paris. The scale of these shows reflected the group’s growing international footprint and the demand that had built since the 2023 documentary.

Contract Renewal Milestone

All five members renewed their contracts with JYP Entertainment in 2026. The announcement came during a fan meeting, and the agency pledged continued support for the group’s push toward global top-girl-group status. The renewal removed any short-term uncertainty and signaled that the members intend to keep working together as a unit for the foreseeable future.

Solo and Individual Ventures

While the group maintained its schedule, individual members began exploring solo work. Yuna released solo material and created viral content that reached new audiences. The rest of the members balanced personal projects with full-group commitments, showing that solo activities could coexist with the core ITZY identity without pulling the lineup apart.

Discography Growth

The catalog expanded quickly after 2023. Releases included GOLD in 2024, followed by Collector, TUNNEL VISION, AIR, and Girls Will Be Girls in 2025. Each project kept the emphasis on personal themes while testing new production directions. The steady output demonstrated that the vulnerability explored during Kill My Doubt was not a one-off experiment but part of an ongoing creative approach.

Sustained Momentum in 2026

The Tunnel Vision tour remained active through mid-2026 with multiple legs across different continents. Regular fan meetings filled gaps between album cycles and kept the connection with supporters strong. Three years after Kill My Doubt, the group continued releasing music, performing at arena scale, and planning ahead, which confirmed that the trajectory set in 2023 had staying power.

The future

ITZY’s post-2023 record shows consistent growth rather than a single breakout moment. Multiple albums, a major world tour, and contract renewals through 2026 established a stable platform for the years ahead. The members have kept the same focus on relatability and self-trust that defined Kill My Doubt, only now with a larger stage and longer timeline to work within.
