The Music Freaks EP 10 prediction

Hi! So this book is just my theory of what'll happen in Episode 10 of The Music Freaks. But I apologize if I get some things wrong, I do not know much about this series, for I just started watching it a few days ago in Youtube. A good friend of mine, who is a fan, also suggested it to me! I just finished watching episode 9, so I wanted to make a short theory after watching all the episodes.

Book cover is Zoey because she's PROBABLY the reason why all this drama happened φ(*￣0￣)

Note: Since this is just my theory of what'll happen in ep 10, I will unpublish it soon, once the episode is released! But for now, here's what I THINK will happen.
