The first post showed two of the winners of the show with captions that read, "My dongsengs! Congratulations Pinky and Im Na Young." 

Then Ailee shared another photo of Pinky, Im Na Young, and Park Siyeon, writing, "I was there at the set to quietly support and cheer, but busted into tears when we reunited after a long time. I am so proud of my dongsengs."

She also added, "For the past 5 years Na Young, Pinky, and Siyeon have always been wonderful. After my debut confirmation, we made a promise in tears about meeting on stage one day. I will never forget that. I am so proud because I know you guys kept on practicing hard without giving up. Unnie adores you guys a lot. I love you." 

What sweet messages! The competition is over, but it's only the beginning for Pledis Girls!

Congratulations girls and good luck!
