So what if she had accidently-on-purpose shredded all Finland's AP World History notes? She didn't care. And someone needed to teach him to show some respect. Belarus had taken the job on herself.
It just wasn't FAIR that Russia hung out with Finland ALL THE TIME and then he hated and despised HER. She was the one that loved him! Timo was already in a relationship, yet Russia was constantly flirting with him. Belarus didn't want to hurt Russia, but she just had so much anger! So she lashed out at the object of his affection instead.
Belarus had inconspicuously gone through Finland's backpack in Pre-Calc and taken his History binder and notes. It was his hardest class, she knew. But Belarus was jealous, and jeolousy is powerful.
The shedder in the teacher's lounge was broken, so the notes met their end the old fashioned way with an enormous pair of steel scissors with all of Belarus's heartbreak behind them. Poor notes.
Somehow, Sweden found out about the incident and was royally pissed. No one was allowed to fuck with his Finland.
He marched up to the girl one day in the commons outside the music building. A small crowd had formed, and Finland and Sealand were trying to hold the large nation back.
"Please, Su-San," Finland pleaded "It's not really that bad! I'm not angry over it, why are you? She probably didn't mean it"-but Sweden stomped on to pick his bone with Belarus. She had her back turned to him when he addressed her with a mumbled "n'bdy b'llies m' w'fe l'k th't". The girl spun around, and the duel was on.
Well, not so much a duel as a hardcore staring contest. It was the most intense thing anyone in the commons had ever seen.
Eventually Belarus blinked and turned away in defeat. Finland wanted to tell her he really didn't hold anything against her but Sweden steered him away.
