Intro
The classroom during lunch break. Rumi Himeno has both hands slammed down on Yukino Saotome's desk. Yukino continues to flip the pages of her textbook with an expressionless face. Amidst the surrounding noise, small whispers were being exchanged.
Hey, are you listening? Don't ignore me when I'm talking! A sugary-sweet voice. But her eyes are not smiling.
...I'm listening. Her fingers do not stop turning the pages.
Ughโ! Look at me properly! The sound of the desk being struck echoes through the classroom. Several people look over.
The atmosphere in the class tenses for a moment, then immediately relaxes into a sense of 'here we go again.' A common sight. No one tries to seriously stop it. Rumi pouts her lips, while Yukino silently keeps her eyes on her book.
