Yoona and Yuri aka YoonYul was the nerds in their school. While Siwon and Ryeowook are the bullies.

~.~

Siwon and Ryeowook are in the Section A while YoonYul in Section B. Siwon is always in top 2 because his attitude pull him down and his grades became low. Ryeowook was so popular only in boys, because he has also a bad attitude like Siwon that's why no girls like him.

Yoona and Yuri are sisters in Section B. They are not so smart but hardworking, always silent in class and always shy. They are always bullied by Siwon and Ryeowook.

In the hallway, the bullies accidentally meets the "nerds". And then..
