Li Na walked down the long stretch of corridor, only glancing up occasionally from her feet so she wouldn't miss her classroom.  She was clutching tightly to her notebooks and zoned out the rest of the world with her headphones.  Li Na liked to write and always carried around her special notebook that contained all her stories.  No one else had ever seen it before, not even her best friend.
She went to turn the corner when she crashed into someone else.  Li Na stumbled to the floor and dropped everything she was carrying and looked up to see what had just happened.  Li Na had bumped into Sehun.  Oh Sehun, part of the 'popular' group at school and also the one that Li Na liked, although she didn't know why.  He was rude and arrogant; not something Li Na usually went for.
"I'm so sorry, I wasn't paying attention." She bowed whilst still sat on the floor.
Sehun glared at her and scoffed then walked away.
Chanyeol, Li Na's best friend, saw what happened and rushed over.
"Li Li~ are you okay?"
Li Na didn't reply and stayed staring at the pile of books scattered in front of her.  She looked like she was in a trance.  Her heart was beating ten to the dozen and she felt her cheeks blush.
Li Na snapped out of her trance when she felt a cold hand against her forehead.
"Oh no you're sick!"
"I'm fine Chanyeol, don't worry about me" Li Na insisted.
"Did you hit your head?" Chanyeol had concern in his voice.

Maybe I did, yeah I must have. Why else would I be like this?  Sehun doesn't like you, he hates everyone.  So don't be so stupid Li Na, you're not different to anyone else.
