[Translator's note] Training implies that Jessica is training the fans with her actions in the video.
On December 2nd’s episode of “Yoo Heeyeol’s Sketchbook”, Jessica discussed the “training video” which has recently become an issue on online communities.
During the broadcast, Jessica said, “There are fans there to take pictures every time we go to the airport, and at the time, there were regular fans that come to see us, and I said hello to them with the thought of, ‘Oh they’re here again’ in mind.”
Jessica’s “training video” became an issue between netizens as a kind of fan service by pointing a finger at the fans who came out to welcome them at the airport.
Netizens responded with, “Training like an ‘Ice-Princess’”, “It was nice to see her treat the fans with friendliness” and “I hope that there will be more training videos in the future.”
