- Su-hyeon: Ji-hyun... At the amusement park... Do you remember the balloons dad bought us? As we fought over the prettier color, the balloon flew up to the sky. I cried, and so did you... So you told me... Later, when I'm grown up, you'd put wings on me. So I could go to the sky and find the balloon... Ji-hyun... Thank you for the wings.
- Hee-ju's ghost in Soo-hyun's body: Teacher. It's me, Hee-ju.
- Ki-seok: [Confused] Soo-hyun...
- Hee-ju's ghost in Soo-hyun's body: I'm Hee-ju, not Soo-hyun... Feel me. I'm not a man anymore.
- Ki-seok: You're not Hee-ju... Hee-ju's dead.
- Hee-ju's ghost in Soo-hyun's body: I'm alive right now! I've waited so long for this moment. I so wanted to reveal myself to you...
- Ki-seok: Hee-ju, it's no use. Let Soo-hyun go. That body isn't yours.
- Hee-ju's ghost in Soo-hyun's body: You liked me. You loved me!
- Ki-seok: I loved you... But ...
- Hee-ju's ghost in Soo-hyun's body: Love is for one person only!... And it never wavers.
