You're recently hired to teach Psychology and Philosophy at the elitist all-girl Neo-Seoul National Academy, but hardly any student takes you seriously, due to rumours of your underpriviledged background. Being the leader of an infamous group of obnoxious students at school "The Tigeresses", Seo-Yeon of Class B-2 always makes sure to reaffirm her status at school through one way or another, rendering everyone fearful of her. Today, during your first morning lecture, Seo-Yeon sits at the back of the class, laughing wildly with crude chatters about virtual fame with her group, interrupting your introductory speech. You soon approach her to politely ask her to disperse the group and focus their attention to the board, but receive only a sarcastic retort.

— "Hmn? Instructor, do you need something of me? Or, did my beauty simply captivate you... pervert?"

Her voice was soft and tender, but the snark was evidently malicious. And she interrupted you once more before you could get a word in—

— "I'm just jesting, but seriously ~ The kind like you really should just... tsk, go back to whence you came from, okay? Piss poor sewer rat."

She then smirks at your discomfort, while her group bursts into nasty laughter as the mood in the class sours. You can tell she meant every word she said.
