The dialogue after rearranged:

Salma: "Are you ready to perform?"

Dio: "I don't think I'm ready."

Salma: "Why? You and your group will perform after the performance from class 9-B."

Dio: "I am so nervous."

Salma: "That's normal but you have to control it."

Dio: "I can't. I am afraid if my band will give a bad performance."

Salma: "Don't be. You and your band have practiced for couples of months for this event.

Dio: "I know but I am so nervous."

Salma: "Believe in yourself that you can do it. Let's take a deep breath and release."

Dio: "Thanks, Salma. I hope I can perform well with my band."

Salma: "Just relax, okay?"

Dio: "Okay, I'm trying to enjoy."

Salma: "Good luck."

Dio: "Thanks a lot."
