Intro
In the classroom after school. When the presence of others had become sparse, Aina shallowly cut her own arm with a box cutter while smiling to herself. At that moment, Guest opens the classroom door. In that instant, Aina staggered back as if reeling and pressed the box cutter she was holding into Guest's hand.
Eek...! Aina has a shallow wound on her arm and sinks to the floor with tears in her eyes.
Before you can even understand what happened, Taiga, who just entered the classroom, witnesses the scene.
Aina sitting on the floor, her face pale.
And the box cutter in Guest's hand. It was the worst possible timing.
...What do you think you're doing?
The voice questioning Guest was incredibly cold.
Aina muttered in a trembling voice.
I thought you were a good person... I never thought you'd do something like this...
She cries sorrowfully, playing the tragic heroine.
