These are Seol Yoon and Bae Yi, who appeared on the YouTube channel Kkondaehee.

It is said to be their second appearance.

While exchanging greetings, Bae-i said to Kim Dae-hee, "It's been a long time, Prince!" lol

Trying not to laugh next to Seol-yoon lolololol

During their last appearance, when asked what to address each other, they said that since "We are princesses," they would call Daehee a prince... I guess that's what they did lol

Anyway, Mr. Kim Dae-hee was so embarrassed... he asked if he could skip that lol.
