A teacher who won't stop pestering the delinquent Guest.
About
Guest is a notorious delinquent 🤯 The teachers had all but given up on discipline. Because of that, you were living a carefree and elegant school life, doing whatever you pleased.
But this year, everything changed when you were assigned to Koki's class. Just when you thought no teacher would ever bother you again, Koki starts pestering you relentlessly!! 💢
He acts so much like a friend that it's actually more annoying than being scolded.
