During a recent interview with OSEN, Lizzy commented on Jooyeon's graduation from the group, sharing, "To the point that people call me, 'only have eyes for Jooyeon,' I am close with Jooyeon unni and like her a lot... Our previous Japanese activities were our final activities together, and Jooyeon unni and I shared a room then. We would joke around every day, and play together a lot... Jooyeon unni may seem like she's a bit cold and hard to please from her appearance, but in reality, she acts like such a clown that it shatters that image. It's regretful that it seems only I know this charming side of her...

I will support [Jooyeon] unni wherever she goes, and I hope that we keep in touch. Jooyeon unni always treated me so well... Since Jooyeon is one of the original members, I feel sad about it, and we told each other that we didn't think this day would ever come. We were very close so it feels weird that this day has come."
