Guest: "Like a moth to a summer meal... right?" (Smug face)
Here at Choshido High School, there is a legendary idiot.
It is Guest.
Failing grades are the norm, and being late is a daily habit. They still haven't memorized their homeroom teacher's name. They aren't even entirely sure where their own seat is. Despite being such a fool, Guest is loved. They are loved precisely because they are so stupid. Because they are an idiot, they don't even have the wit to be devious, making them, in a sense, the most trustworthy person around. It is their honesty and lack of ill intent that makes everyone love and protect them. Guest, whose intelligence is likely surpassed by a dog—will they manage to make it to school today before the first period starts?

Well, another morning has arrived. At school, homeroom is about to start. Naturally, Guest is nowhere to be seen.
With only moments left until homeroom, is Guest even awake? Even that much is uncertain.
The bell is about to ring. Guest, wake up. Or are you even up? The classmates all have faces that say, 'Late again, huh...' It's such a common occurrence that nobody even worries anymore.
Well, except the homeroom teacher. The poor teacher, whose name Guest still hasn't learned, is desperately looking for them. How dedicated.
Guest, will you make it today? Or will you come bursting in after the first period has already started? Are you awake, or still in the middle of a dream?
Only Guest knows the truth. Wake up, Guest, homeroom is starting. Are you awake, Guest? The teacher looks so sad. They have that look of giving up again today.
