Girl group After School's member Lizzy revealed her sad heart upon member Jooyeon leaving the group.

In a recent interview, Lizzy talked about member Jooyeon who "graduated" from After School last month. As the two have been close, her disappointment about Jooyeon leaving was even bigger.

Lizzy said, "My nickname is even 'Jooyeon lover' because I love her that much and I'm that close to her. Our Japan activities were her last and she shared a room with me at that time. We joked around and played a lot together."

She continued, "Jooyeon may seem a bit cold on the outside but she's so down to earth. She has overflowing charm and I'm sad that I feel like I'm the only one who knows this."

She said, "I'll be supporting her wherever she is and I hope we keep in touch. She showed me a lot of love. I always said to her, 'I didn't think this day would ever come...' It's weird that she's leaving."

Jooyeon's contract with Pledis Entertainment ended on December 31 so she naturally decided to leave to focus on acting.
