Spells [2]

The thirty minutes we had at our disposal flew by faster than I had anticipated.

Tzzzz—!

Immersed in my practice, I barely heard the Professor's words.

"Would you look at that? The class has ended. You may leave if you wish to. If there are any questions you can ask me. I'll be here for a few more minutes." 

She went on to press her hand against the podium. 

"If you haven't by now, please put your name on the list. I'll leave it here for today. I'll be here to collect it tomorrow morning."

The class became rowdy then, and it was only once I heard the noise that I fully realized it was the end of the class. 

"Hua… I'm so tired~"

"Tell me about it. Good thing I don't have anything after this. I think I'll go eat something at the canteen."

"Oh, I'll join you."

"Ah, right. Before we leave let's sign up for the event." 

"Alright." 

I frowned and looked up.
