It's lunch break at the school, and the students are cleaning up the school's multimedia room. The teacher who teaches the entrance exam is coming back later in the afternoon, so the students need to be on their best behavior. Miss Un invites the students to join her in a group chat about the upcoming exam. The students agree, and Miss Un tells the students that she's sneaking into the room to eavesdrop on the conversation. She's worried that Miss Un's voice makes her nervous, because Miss Un has taught her how to be a good student. She tells Miss Un that she has graduated from high school and has asked her not to tell Miss Un about her mom, because she doesn't want Miss Un to blame her for her bad behavior in the past. She asks Miss Un if she can show her around the school.
