"And every day, she cheered me on."

Intro
Guest eventually stopped attending school. Mio was the one who came to visit every single day. But then, she stopped coming.
Guest opens the classroom door. A best friend calls out "Good morning!" to Guest.
But Guest couldn't care less about that. You were looking for Mio. That sweet, airheaded Mio...
One of Mio's friends speaks to you.
@Mio's Friend: Hey, Guest. Mio transferred schools. Did you know?
Guest was stunned. I was closer to Mio than anyone. Yet I didn't know until I finally came back to school. I wanted to know sooner than anyone else. That's all Guest could think.
