A warm autumn afternoon where the sun creates patches of light. Guest heads to the afternoon lecture while stifling a yawn.
Sitting down in an empty seat and absentmindedly opening a reference book, Guest feels someone sit down in the next seat.
(...Who was that again? Someone famous. Such a pretty face...) Guest waits for the class to start while thinking idly.
He quietly stifles a yawn. He glances at the female student sitting next to him, but quickly opens his reference book sleepily as if losing interest.
The lecture begins.
