FLARE U is making its official debut with “WAY 2 U,” the title track from the duo’s first mini album, “YOUTH ERROR.” The FLARE U debut is set for May 13, 2026, with all tracks from the album scheduled for release on music platforms at 6 p.m. KST, followed by a “Debut News” event in Seoul at 8 p.m. KST. 1
The new act consists of Choi Rip-woo and Kang Woo-jin, both known from Mnet’s “Boys II Planet.” The project is being presented by FNC Entertainment, which began the rollout by opening FLARE U’s official social media channels on April 24 and introducing the team name with a trailer video, mood image and official logo. 2
‘WAY 2 U’ Opens the FLARE U Debut Era

“WAY 2 U” is the title track of “YOUTH ERROR” and the central focus of FLARE U’s debut campaign. FNC Entertainment first released the music video teaser for the track through official social media on May 11, with the teaser showing Choi Rip-woo and Kang Woo-jin in a gymnasium setting alongside a bright sound and a partial look at the performance. 3
The full “WAY 2 U” music video is scheduled to arrive at the same time as the album, at 6 p.m. KST on May 13. 3 That timing places the title track at the center of a release-day sequence that also includes the publication of the full mini album and the evening debut event at Blue Square in Seoul. 1
Before the official release, FLARE U also previewed material from “YOUTH ERROR” during KCON JAPAN 2026. The event was held from May 8 to 10 at Makuhari Messe in Chiba, Japan, and the duo appeared as special performers before the formal debut date. Their reported X STAGE set on May 9 included “WAY 2 U,” “Hyper” and “WOO-HOO,” giving audiences an early look at three tracks from the debut record. 4

‘YOUTH ERROR’ Tracklist and Pre-Release Rollout
The debut mini album contains six tracks: “WAY 2 U,” “Hyper,” “우니까 (Don’t Cry),” “MIRACLE,” “WOO-HOO” and “놀이터 (Playground).” KBS WORLD reported that FNC Entertainment revealed the album’s tracklist poster through official social media on April 27. 5
The sequencing described in later album preview coverage places “WAY 2 U” as the opening track, followed by “Hyper,” “Don’t Cry,” “Miracle,” “WOO-HOO” and “Playground.” 6 The available source material does not provide songwriter, producer or genre-credit details for the individual tracks, so the confirmed album information remains focused on the title track, the six-song list and the scheduled release time.
The highlight medley film served as another step in the pre-release campaign, previewing the album’s overall sound before the May 13 release. 6 In the reporting available, “WAY 2 U” is positioned both as the title track and as the first song in the album sequence, making it the lead entry point for listeners approaching FLARE U’s first release.
FLARE U’s public identity was introduced in late April, when the team name was announced with official visual material. Dispatch reported that the name refers to two sparkles becoming one light, with that light completed when the members meet fans. 2 The explanation connects the duo format directly to the group’s branding, while the debut material places Choi Rip-woo and Kang Woo-jin together across teaser, performance and album promotions.
Seoul Event Follows May 13 Release
Following the digital release of “YOUTH ERROR” and the “WAY 2 U” music video, FLARE U is scheduled to hold “Debut News” at Blue Square Woori WON Banking Hall in Seoul at 8 p.m. KST on May 13. 3 The event comes two hours after the album release window, making it part of the same-day debut schedule rather than a separate later promotion.
The May 13 schedule follows a compressed rollout that began with the social media launch and name reveal on April 24, continued with the April 27 tracklist poster, added the May 11 music video teaser, and included live previews at KCON JAPAN 2026 before the official debut. 5 4

With “WAY 2 U” leading the six-track “YOUTH ERROR” release, FLARE U’s debut is built around a clearly dated album launch, a same-day Seoul event and pre-release performances that introduced key songs before the official arrival. The confirmed details place Choi Rip-woo and Kang Woo-jin’s first activity as FLARE U on May 13, 2026, with “WAY 2 U” serving as the title track for the duo’s opening release.
