Sun-Young asks her superior Ho-Jun to train her in a Master-Slave BDSM dynamic. His first command is for her to wear a vibrator while walking around. His second command is for her to perform oral sex on him under a table. She keeps his ejaculate in her mouth for the remainder of the workday, which immensely satisfies him. He then rushes her home for an intense sexual encounter.
After rescuing his Ajumma, MC faints and then he wakes to Junghee by his side in the hospital room. He gets a boner from his Ajumma's hugs. She then proceeds to relief him.
