On July 31 Kahi sent a Tweet to Lizzy, who just had her birthday. She wrote, "You got a year older? Are you not a baby anymore? Happy birthday, Park Sooyoung~ Live beautifully."

After School has a unique system where members are admitted and graduated. Kahi was the leader since the debut of the group, and she recently graduated. Since then, they recruited a new member Ga Eun as they came out with their new song, "Flashback," which has been a success.

Kahi's affectionate words lead Lizzy to comment on a recent horseback riding photo of Kahi. She wrote, "Kahi, did you fall in love with the horse? I miss you. Thank you." The two showed their close ties through their conversation.

Viewers commented, "The oldest and the youngest have their unique conversation. Now Lizzy's not the youngest member but she still has the most young member love!" They also wrote, "Why is their conversation so cute?" and, "Kahi, we miss you!"
