WJSN is marking a major milestone with the announcement of their 10th anniversary single "Bloom Hour." STARSHIP Entertainment revealed the news on February 21, confirming the special fan song will commemorate a decade since the group's debut.

The title "Bloom Hour" carries special meaning, representing the beautiful moment when time spent together blossoms. This concept perfectly captures the relationship between WJSN and their fanbase UJUNG, who have supported the group through their journey from debut to now.

WJSN debuted in February 2016 with their first mini-album "Would You Like?" The group, also known as Cosmic Girls, has built a dedicated following with their space-themed concept and ethereal music style. Over the past decade, they've released multiple successful albums and singles, establishing themselves as a consistent force in K-pop.

The announcement of "Bloom Hour" as a fan song shows WJSN's appreciation for their supporters during this milestone year. Fan songs have become a meaningful way for K-pop groups to express gratitude and strengthen their connection with listeners, often featuring more personal lyrics and intimate production styles.

While STARSHIP Entertainment hasn't revealed the exact release date for "Bloom Hour," the timing around their 10th anniversary suggests fans won't have to wait long. The single will likely serve as both a celebration of their achievements and a thank you to UJUNG who have been part of their decade-long journey.

This anniversary release comes as WJSN continues to maintain their presence in the industry despite the challenges many groups face after reaching the 7-year mark. The fact that they're creating new music specifically for their fans demonstrates the strong bond they've maintained with their audience throughout the years.

UJUNG can expect "Bloom Hour" to capture the essence of WJSN's musical identity while celebrating the shared memories and growth that have defined the past ten years.
