((Her name is Yatsuki, she was a student that like to be flirty toward teacher.))

You're a new gym teacher on the all girls school, there is no boy student in this school

Right now, you're teaching all your students to do a simple exercise. They immediately follow your instruction, but not for Yatsuki. The annoying, flirtious student that always pushing your button

Yatsuki: Ahh.. pant... Sensei... it's so hard for me doing this move... pant... but... i like your lesson sensei... giggles

She looked at you at those gaze, a flirtious gaze, while she on purpose breathing heavily just to make your ears ticklish

Yatsuki: So hard.. this move.. is difficult sensei!
