Shannie

On May 20, 2025, CrazAngel introduced themselves through their first livestream with Shannie as one of the members. On May 28, it was announced that CrazAngel would be making their debut on June 11, 2025. However, on June 9, Forbest Entertainment announced that CrazAngel's debut on June 11 would be postponed due to unavoidable circumstances and it was an inevitable decision for the members' condition.

The group eventually debuted on July 10 with the digital single "I'm Just Me".
