In the video, Kim Dae-hee asked Bae, whom he met for the first time, if her real name was also Bae. In response, Bae said, “My real name is Bae Jin-sol” .

Later, Bae introduced herself, saying “I was born in Busan, and then I moved to Yangsan” . Hearing that, Kim Dae-hee said, “Then your background is similar to aespa’s Winter.”
Bae added, “That’s right. I went to the same high school as Winter” , revealing that the two are alumni.
When Kim Dae-hee said, “I know I’m older than you, but just call me as you like! You don’t need to call me ‘sir'” , Lily and Bae replied, “Sure!” , with bright smiles. The two then said, “We call each other Princess all the time. It’s a nickname. It’s like, ‘Princess! That’s not how you should do it’. We point each other out, but this makes it less insulting” , drawing laughter.
