Lee Chang-sub’s Ballad ‘I’ll Be Your Flower’ Blossoms with Star-Studded Vocal Challenge

Lee Chang-sub, the singer and musical actor best known as a member of BTOB, continues to enchant K-pop and ballad fans with his latest digital single, ‘I’ll Be Your Flower’. Released on June 12, the track is not only winning hearts through its audio release but also through a blooming viral challenge video series featured on his official YouTube channel, Changtagio.

‘I’ll Be Your Flower’ is an emotional ballad that beautifully expresses the desire to become a flower and forest for a loved one. The song was penned, composed, and produced by singer-songwriter Roy Kim, marking his first official collaboration with Lee Chang-sub and resulting in a powerful musical synergy.

The song’s emotive qualities are further amplified by a vocal challenge that continues to gain momentum online. Several renowned artists—including Jung Seung-hwan, Wendy (Red Velvet), Lee Mujin, Choi Yu-ri, Dvzan (formerly Daybreak), Roy Kim himself, Yuju (formerly of GFRIEND), and Lee Hong-gi (FTISLAND)—have lent their unique voices to sing the song’s poignant chorus.

The result is a tapestry of voices that transcend genre and generation, delivering fresh emotional depth to ‘I’ll Be Your Flower.’ Notably, Roy Kim’s own participation in the challenge has delighted fans, showcasing his personal investment in the project.

Two main versions of the challenge are circulating the web, fostering widespread fan engagement: one where artists sing along to piano accompaniment played by Lee Chang-sub and another where they split parts of the chorus with him. These clips have taken social media by storm, inviting netizens to take part in the growing phenomenon.

Lee Chang-sub has also been actively performing the song live at various university festivals and in digital content, offering audiences a moment of heartfelt comfort and emotional healing. His sincere vocal tone and emotional delivery have captured the hearts of younger viewers in particular.

In addition to ‘I’ll Be Your Flower,’ Lee Chang-sub continues to showcase his musical versatility. He recently released another single titled ‘Feel The Groove’, a remake of the song ‘겁쟁이’, and contributed to an Original Soundtrack (OST). His artistic calendar remains packed, with his return as Huey in the upcoming musical ‘Memphis’ revival opening June 17, and a slated performance at the 2025 Weverse Con Festival.

Lee Chang-sub is reminding the world that flowers bloom not only in gardens but through passion, artistry, and connection—one unforgettable note at a time.
