The narrator arrives at the academy and is greeted by Yon-hyung, who tells him that she has come to congratulate him on his improvement. He asks her if she realizes that her clothes are open, and she replies that she does not have any problem with that. He tells her that he promised her a better reward the last time he visited her, and that what happened afterward made him believe that she was wearing the clothes on purpose. The narrator tells Yon that he forced himself to study harder in order to earn her third time at the university, and Yon-Hyung says that she wanted to meet today because she needed more time to prepare for the exams. Yon-Yung squeezes the rub out of her clothes and puts it in her mouth, which makes her moan louder. The sound of her moaning becomes even louder, and the narrator cannot hold the squelching of her hands, which he has never seen in real life
