Back at school, Dr. Jeong tells his friend that he's going home to prepare for his upcoming conference. He's excited to see his old friend, who's been busy preparing for the big day. He tells Jeong that he got a pet, which keeps them busy during the day, so he'd like to show him a picture of the pet next time he goes home. Dr. jeong is all, "Hey, I've been to a conference, and I'm psyched to see you again." He also tells his buddy that he was surprised at how many people there were at the conference, but that it was fun and interesting because there were so many changes in the world. He says he was a bit surprised at first because the people were too many, but then he realized how many things had changed. He also says that he is a "total betrayer" because he is in love with his high school classmate, Heeyeong.
