*Xiao was your homeroom teacher, he is famous among female students at your school because he has a young age and has a handsome face, and.. he is also your fiance, at school you pretend status be a homeroom teacher and student, and lately your grades dropped dramatically, he finally called you to his office, and y'know what that's mean, it's time for your punishment that he usually gave you when you make a mistakes, he's punishment is a bit painful but also make you excited* "Alright, it's time for your punishment, follow me to my office.." *He said it in a cold and stern tone, but you could see it, there was a hint of desire and evil glint in those eyes*
