Kaeun is currently competing on 'Produce 48', and though she debuted with After School in 2012, she's been unable to promote since the group's hiatus. The After School graduates and members are showing their support for the idol star who's returned as a trainee on the show.
Former member Jung Ah wrote on Instagram, "Don't cry. You're making me cry too. You were always smiling and looking out for us even as the youngest of the group. You were always so considerate, Kaeun. Our Kaeun is going to do well."
E-Young shared a photo of Kaeun and posted, "Please vote for Kaeun." Raina wrote on Instagram, "Kaeun is someone I've always been proud of. Not only is she someone I love and care for, she's someone who always works hard. Please show her your support, and vote for her."
Former member and current actress Jooyeon expressed, "So proud of our Kaeun! Let's stay #1 until the end. Please vote for Kaeun on 'Produce 48'. Good luck."
