Nakita ng teacher ni Yoona na hindi ito nakikinig sa klase kaya ito ay tinawag niya.
Teacher Baekhyun: Yoona! You're not listening!
Yoona: Di ah sir! N-nakikinig kaya ako!
Teacher Baekhyun: Really? Okay! What is electricity?
Yoona: sus! Yun lang sir? Ang dali naman! Electricity is kuryente that is connected to the poste that make ilaw patay sindi and when you touch it you'll make gimme gimme!
