WJSN Celebrates 10th Debut Anniversary with Heartfelt Fan Song ‘Bloom Hour’

WJSN has marked a meaningful milestone in its career with a special release for fans. The group dropped the anniversary single Bloom Hour on February 25, commemorating 10 years since its debut and expressing gratitude to its fandom through music.

A 10-year promise told through two songs

Released at 6 p.m. KST on major streaming platforms, the special single includes the title track “Bloom Hour” and the B-side “Mirror.”

Both songs reflect the journey WJSN and its fandom have shared across countless seasons. While “Bloom Hour” focuses on the bond that has grown over time, “Mirror” presents a parallel perspective on the group’s past and future, highlighting their evolving story as artists.

The release arriving on the exact date of their debut adds symbolic weight, turning the project into more than just new music. It becomes a timestamp for a decade of memories.

A sincere message for UJUNG

Through the fan song, WJSN revisits its relationship with UJUNG and delivers a more honest and mature narrative shaped by years of experience.

The members’ voices carry not only musical growth but also the emotions of artists who have spent a long time with the same supporters. That sincerity is expected to resonate strongly with fans who have stayed through every era.

Reuniting despite busy individual schedules

In recent years, WJSN members have expanded their individual careers into acting, variety shows, musicals and solo music activities. As those schedules increased, group promotions naturally became less frequent.

Even so, the members reunited for the 10th anniversary project, demonstrating their lasting affection for the team and its fandom. Their return as a full group after focusing on separate paths is drawing attention to the new synergy created by their strengthened skills and deeper artistic identities.

A decade of signature songs and steady growth

Since debuting on February 25, 2016, WJSN has built a distinctive discography with tracks such as “Secret,” “I Wish,” “Dreams Come True,” “Save Me, Save You,” “As You Wish,” and “UNNATURAL.”

Each era contributed to the group’s expanding universe-like concept and emotional storytelling, helping them secure a loyal global fanbase.

Anniversary live broadcast with fans

Ahead of the release, the group held a special talk live on its official YouTube channel on the night of February 24. The broadcast served as a space to look back on the past decade together with fans.

During the live, the members shared memories, celebrated the anniversary in real time and expressed their gratitude for the unwavering support that made the 10-year journey possible.

A milestone that looks toward the future

Rather than closing a chapter, Bloom Hour acts as a bridge between WJSN’s past and what lies ahead.

With members returning as more complete performers and storytellers, the anniversary single carries a message that their shared time with UJUNG is still in full bloom.
