Baekhyun doesn't like to think of himself as a bullyer, he isn't the nicest kid in the class and he surely does not consider people's feelings -at all- that much, but it's not like he finds joy in making people suffer, he simply just does not care.

However, things might change a little when he finds one of his classmate's diary, Lim Nahyun's, the marry-go-happy girl, the so-called nicest girl of the school.. or that's how she pretends to be, because clearly she isn't.
