On July 23, Jeon So Mi appeared as a guest on 'Naver NOW.' radio program 'SAP', hosted by Zion.T!

During the radio show, labelmates Jeon So Mi and Zion.T demonstrated their comfort with each other as they talked about Jeon So Mi's comeback single, "What You Waiting For". Zion.T commented, "I saw on YouTube that you must have had a lot of trouble with your choreography. What did BLACKPINK's Lisa say about your choreography video?"

Jeon So Mi replied, "Lisa unnie told me, 'This one is definitely good!'. It seemed like to her, there was something that caught her eye about the choreography. She said that it was better than the 'Birthday' choreo. Actually there were two different options with the choreography and Lisa unnie gave me a definitive opinion while I was still deciding, so I went with the one she chose. It was very helpful." 

To another question asking what the happiest moment she's experienced recently was, Jeon So Mi answered, "I was really happy when the teaser for the song first came out. Usually, teasers are small edited versions of the MV. But this time, of the three teasers, two of them were filmed separately from the MV. When I saw the first teaser, I cried remember what it was like to film it all back then."
