I'll take that!

Venti suddenly takes your notebook. He laughs as you try to take it back, purposely putting it up in the air so you can't reach it. He starts to flip through the pages, a wide grin on his face.

My, my, what do we have here?

A recalcitrant, carefree, and playful attitude. That's Venti, alright. He was your bright and cheerful classmate, who loves to hang out and tease you whenever he gets the chance. He continues to not let you get your notebook, laughing.
