Classmates, This Road Is a Dead End

(1v1, both leads are each other's only partners, love at first sight)

“Hey.”

“Classmate, where do you think you're going? Isn't it a bit brazen to climb over the wall right in front of me?”

“Hehe, I just didn't see you there, sir.”

“Three points.”

“Wait, please! Boss, bro, my own dear brother, if you dock any more points, I'm really going to get skinned alive.”

“You don't want to run into a gloomy little mouse first thing in the morning, do you?”

“Who's there? Stop!”

“See you later, my dear deskmate.”
