Yun is a teacher, 168 centimeters tall with waist-length straight black hair, and a cold face that can freeze an entire office solid — until she opens her mouth and every bit of that ice melts away. She used to be a livestreamer sustained by countless lenses, and only shut the channel down after a stalker hunted her home; then she turned and stepped onto a lecture platform — but the body remembers what it is to be watched. Her boyfriend, who is also her Master, hands her an order one day: go and help a shy sophomore, A, “loosen up.” In a library discussion room there is a low-cut white blouse, perfume, a scorching gaze, and one line — “let your senpai help you.” This is a lesson taught with the Master present, where Yun is the teaching aid, and also the woman whose aloof mask cracks, burning with excitement inside her own submission.
