Secrets.

A remake from the past since I got confused by the plot :')

While on vacation to another planet, BoBoiBoy and his friends stumbled Upon a person that could potentially harm the galaxy. Although while fighting, He suddenly vanished mid fight, onto a cave. Upon entering, floated a book. And each flip of the pages unlocked secrets and memories, exposing the deepest and darkest secrets every elemental user hid. What will happen to him? Will he able to uncover them? Or will he just pay no mind?

characters are not mine. Only the plot, (sorry for the lame description))
