After School shared on their official Facebook, "The common dressing room scenery of girl groups! Jooyeon with Kaeun's tangled hair! The moment she grabs it! Jooyeon, who spotted the camera, turned into JuPal!! Honestly, all of the After School members are pranksters. We don't know how they've kept it hidden for so long~!"

It seems it doesn't take much for Jooyeon to transform into her rougher alter ago. All you need is some of Kaeun's braids for her to get silly as JuPal, who fans don't get to see much onstage.

Fans commented, "Jooyeon always seemed so chic, but it turns out that she is a prankster," "I didn't know they could have so much fun in the dressing room," and "After School's teamwork is the best!"
