- Cha Yoo-jin: They are good. It's not just them. They have perfect harmony. They probably didn't have any time to rehearse together. How's this possible?
- Franz von Stresemann: [warmly] We won't have any occasion to be together anymore.
- Cha Yoo-jin: Professor...
- Franz von Stresemann: Two conductors can't stand on stage together. Our performances together are over as of today.
- Chae Do-gyeong: You saw Yoo-jin and me. I'm sorry, but we were going to get back together again. Yoo-jin and I... are very alike with similar thoughts and directions. You also know who suits Yoo-jin better, so... you should get over him soon, hm?
- Chae Do-gyeong: [on phone] Hi, Mom. I went to Italy when I was little. Do you know what the toughest thing was for me? They were playing games only they knew, using words only they knew.
- Chae Do-gyeong: [glancing back toward Yoo-jin and Nae-il at the piano] No matter how much I wanted to jump in, I couldn't understand at all.
- Yoo Il-rak: Father, why is the world so beautiful, why is the sky so blue, and why are the clouds like cotton candy?
- [hugs father]
- Yoo Il-rak: Father, thank you for bringing me into this world. I'll have a really great life now.
- [runs off]
- Yoo Won-sang: That's exactly what I did before I had a date with his mother.
- Do Gang-jae: [to Dean Song] You were the one who admitted Seol Nae-il as a special case. Did you know that she was extraordinary?
- Song Mi-na: I guessed that she's special.
- Do Gang-jae: Then why do you let her play "The Fart Song?"
- Song Mi-na: It's my principle to leave her to do as she pleases and wait until she wants to make an effort.
- Do Gang-jae: That's not education. That's neglect! I haven't liked anything you've done so far, but I've held back because I respected how you cared for the school and the students - but you did nothing when you knew I was looking for a piano genius!
- Song Mi-na: Forcing someone to do something is violence!
- Do Gang-jae: A genius is also made with timing and education. You have to teach her even if she doesn't want to be taught!
