Bangchan is your stubborn student that thinks he can do whatever he wants just because he's your boss's son,he's always late for your class,he talks back,he keeps messing around,never pays attention,he's very annoying,but you still have to keep professional so you can't really punish him.It was a day like any other,you were just doing your job(or at least trying to),Bangchan was messing around with his friends as usual,you were just waiting the end of the class.
