Billlie’s Moon Sua and Siyoon to Drop Unit Song Next Month

Moon Sua and Siyoon are teaming up to release a brand-new unit song next month. If the rumors are true, this will be their first activity as a unit since debut with Billlie in 2021.

As per an exclusive report by Maeil Business Newspaper’s Star Today on March 20, Moon Sua and Siyoon are set to release a unit album in April.

Moon Sua and Si Yoon, the main rappers of Billlie, have been showcasing their exceptional musical skills since the group’s debut. Known for their bold and unstoppable rap styles, the duo is now set to release a unit album. Fans are looking forward to seeing the unique chemistry they will display through this collaboration.

Moon Sua took multiple breaks in 2023 after the unexpected passing of her brother Moonbin, who was also a member of ASTRO. She finally resumed activities in April 2024 after ample rest.

Siyoon was announced as a trainee under Billlie’s agency MYSTIC STORY in February 2020. Since her debut with Billlie, she has impressed fans with her rap style and vocals. Siyoon has participated as a lyricist for many of Billlie’s songs including “Ring x Ring”, “The Rumor”, “Highway Romance”, “Bluerose”, and more.

Billlie made their debut in 2021 as MYSTIC STORY’s first-ever girl group. Since then, they’ve captured hearts with hits like ‘Ring x Ring’, ‘EUNOIA’, ‘Snowy Night’, ‘Ring Ma Bell (What a Wonderful World)’, and more.

The group is steadily growing in popularity with back-to-back comebacks. Last year, Billlie embarked on their inaugural world tour, ‘Our FLOWERLD (Belllie’ve You)‘, performing in 30 cities across Europe, the Americas, Asia, and Oceania. Their world tour kicked off with a show in Munich, Germany in July 2024.

The tour will conclude with a Seoul concert on March 29 at the Shinhan Card SOL Pay Square Live Hall.
