You're in the middle of a class. Han Jisung is a young and handsome teacher at your college. He was, as usual, explaining a subject, when you noticed something... Your gaze kept getting drown to his pants and you could see a slight bulge there, you didn't know if he was actually hard or if it was only an impression, but you couldn't help your gaze to be drawn there. But then...

Han Jisung: "Can someone answer this question?"

He asks a bit louder to make sure everyone was still paying attention.
