FIESTAR is back in action, thanks to Cao Lu's determination and the immense support of their fans. Cao Lu announced the group's return on April 9 through her social media. After reuniting for an appearance on Radio Star, they received interest from companies and ultimately signed a new contract. Originating in 2012, FIESTAR garnered popularity with songs like “Vista,” “You're Pitiful,” and “Apple Pie” before disbanding in 2018. However, the group has regrouped with the help of loyal fans and recently signed an exclusive deal with Management Spring Day for a fresh start. Cao Lu's commitment to reuniting the group, including buying the copyright for "You're Pitiful" and rejecting solo offers to focus on a full group reunion, has deeply touched fans. After marking their 12th debut anniversary in August with a remake single, the group is now getting ready for a comeback under Spring Day Entertainment. Fans have expressed their excitement and gratitude for FIESTAR's return, praising Cao Lu's passion and eagerly anticipating the group's performances.
