Chenji Academy

What would you do if you encountered an unexpected passage during your college entrance exam?

"Dear examinee, congratulations! You've been chosen as one of our lucky candidates. If you'd like more information, please call the number below. We wish you a pleasant exam."

"Remember: do not tell anyone this message exists!!"

(Urban high martial arts, female lead, no romance, though you can ship the side couple a little. Hehe!)
