OH MY GIRL member Hyojung released the digital single “Purple Note” at 6 p.m. KST on May 21, 2026, through online music platforms. The Hyojung Purple Note release centers on “나의 작은 청춘에게,” rendered in English reports as “To My Little Youth” or “To My Small Youth,” and is presented as a solo project connected to her early memories of music and school days. 1
The single arrives with three tracks: the title song “나의 작은 청춘에게,” “Look Around,” and an instrumental version of the title track. Hyojung participated in writing and composing all tracks, with Korean reports describing the project as an autobiographical release that places her own story into the music. 2
Hyojung Purple Note Draws On A Real Band-Club Name

“Purple Note” is not only the title of the digital single. Reports state that the name comes from the band club where Hyojung was active as a vocalist during high school, giving the release a direct link to the beginning of her music journey. 3
That background shapes the project’s framing. Dispatch / DIPE reported earlier in the rollout that the single looks back to the starting point of Hyojung’s musical path, while allkpop described the album name as coming from the high school band club connected to her vocalist days. 4 The same theme is reflected in the music-video materials, which place school-age aspiration beside the present-day artist.
WM Entertainment, cited in Korean press coverage, said Hyojung would deliver “sincere messages to listeners based on her autobiographical story.” 4 RBW/WM Entertainment also said, in a Korean-language statement carried by Edaily, that Hyojung participated directly in the lyrics and composition of every track and put an autobiographical story into the music. 2

Three Tracks Led By “나의 작은 청춘에게”
The title track, “나의 작은 청춘에게,” is described as a pop-rock song built around band sounds and Hyojung’s bright vocals. Edaily reported that the song carries a message about courage to move forward, while OSEN emphasized its band-centered arrangement and vocal tone. 1
The second track, “Look Around,” is described as a ballad about the strength found in time spent with precious people nearby. The single also includes the instrumental version of “나의 작은 청춘에게,” completing the three-track release. 2
The tracklist had been unveiled before release. Dispatch / DIPE reported on May 12 that Hyojung would release her first digital single “Purple Note” on May 21 at 6 p.m. KST, after the tracklist was revealed on May 11. That report listed “To My Small Youth,” “Look Around,” and “To My Small Youth (Inst.).” 4
“Purple Note” follows Hyojung’s December 2024 special single “크리스마스 야간열차,” according to OSEN. The new release therefore extends her solo activity with a project more directly framed around school memories, songwriting participation, and the imagery of youth. 1
Teaser And Music Video Present Past And Present Hyojung
Before the full release, Hyojung posted a music-video teaser for “나의 작은 청춘에게” on OH MY GIRL’s official YouTube channel on May 19. OSEN reported on May 20 that the teaser drew on her real school days, when she was quietly developing her dream of becoming a singer. 5
Allkpop’s May 19 report described the teaser as showing Hyojung in a summer school uniform and presenting two versions of the singer: a student dreaming of becoming a singer and her present self after fulfilling that dream. The same report identified “To My Little Youth” as part of her first digital single album “Purple Note,” scheduled for release on May 21 at 6 p.m. KST. 6
After release, allkpop reported that Hyojung unveiled the music video for “To My Little Youth” alongside the May 21 launch of “Purple Note.” The report said the video alternates between high-school-era Hyojung pursuing a singing dream and present-day Hyojung after achieving it, matching the autobiographical framing repeated across the release coverage. 3

With “Purple Note,” Hyojung’s solo release is positioned around a specific personal reference point: the band-club name tied to her high school years. The confirmed release details, three-track structure, self-participation in writing and composition, and music-video narrative all point to a project built around youth, memory, and the early foundations of her music career.
