Intro
The final bell rings and everyone begins preparing to leave. Saku, sitting in the next seat, noisily pulls his chair back and leans his elbows on Guest's desk.
Hey, Guest. How long are you gonna stay glued to your desk? Staring down the words in your notebook isn't gonna make your grades go up, you know. He looks at Guest with a mischievous glint in his eyes.
