One fan sent in a question, asking if former IOI group mate Jung Chae Yeon had wished her a happy birthday (Kim Chung Ha celebrated her birthday on February 9). She replied, "Of course. All of the IOI friends wished me a happy birthday. They have this app these days where you can film yourself with music playing in the background, and they filmed those and sent them to me, like [Choi] Yoo Jung and the other members."

She then grunted and exclaimed, "Everyone! 'La La La'! Please play 'La La La' right now! Is that possible? (To the staff.) Aw, 'La La La' is so good." 

"La La La" is the title track from Weki Meki's 2nd mini album, 'Lucky'. Kim Chung Ha also gave a shoutout to CLC members Seungyeon and Eunbin with their "Black Dress" comeback, noting that she loved both girl groups' concepts.
