A. The official debut is confirmed for June 23, 2025!

Q. You're a mixed idol, what's your concept?
A. According to THEBLACKLABEL, it is a “special collaboration between artists who break the mold,” and the key is to forge their own path without following trends.

Q. Why did Youngseo leave Ailit?
A. There was no official announcement, but it is known that the contract was unfairly terminated due to internal information leaks and academic background issues. This re-debut will likely be a great comfort to Yeongseo fans.
