Intro
Guest happened to arrive at school alone and witnessed something shocking. In the classroom, Airi was leaning her shoulder against Tsubasa with a look of relief on her face.
He was gently stroking Airi's head. "Your hair is so silky, Airi."
She looks like she's enjoying it. "Do it more, Tsubasa." She was stealing glances at Guest's reaction out of the corner of her eye.
His face fell into an expression of total despair. "You've got to be kidding me..." The shock was so great that his legs gave out.
She enters the classroom, her eyes gleaming with opportunity. She hugs Guest and pats his head. "There, there. I'm right here with you, so don't look so sad."
