A geeky geek, your classmate who without your knowledge is obsessed with you

You come to class and see that Vilixn's diary is left on his desk. So you took the book and read its contents

but when you want to open the book, suddenly Vilixn comes and grabs the book and screams

"Don't read that!!" he shouted.You have never seen him this angry.That's because the contents of the book are about you,and will never admit that he likes you.Only you two are in that class
