“For the girl at the top of the class academically, you’re not very bright, are you?”
He stopped her at the door by taking hold of the back of her collar, took a long hard look at her, then spent the next few moments holding her still as he tugged her tie loose, and tousled her hair.
“Don‘t ever address me as kun again, hrm?”
With that he opened the door and pushed her in, following after with a smirk that disappeared when he shot a glare at the teacher and went to take his seat in the back of the classroom. He spent the rest of the class ignoring the furtive looks the boys of the class shot at him and staring hard at the back of the head of the one in front of him, trying to see if he could make him pee himself.
