Naeun becomes Siwoo's little bitch. Her master orders her around anywhere, anytime whether it be the in the classroom, in the streets, in the restroom. He explores his slave's exhibitionist kinks and fucks in the restroom at Christmas eve.
Do-hoon meets up with Seo Ye-Eun at So-mi's workplace (Caffe) to discuss the latter's relationship with her father to furthermore understand her psychology. When Do-hoon gets his answers Ye-Eun tries to leave but he doesn't let her go and punishes her for putting him in a bad situation (That's his actual reason for the meetup). It turns out that she came to the caffe commando as he asked. While they were kissing, Ah-young (So-mi's little sister) happened to be at the caffe with a friend, when she saw Do-hoon, she follows him and takes peeks at him and Ye-Eun kissing. Do-hoon notices people's noise just outside and rushes upstairs to continue humiliating Ye-Eun.
Do-hoon continues taming his boss Mrs. Lee, this time by inviting her over drinks to then take her to a dark alley outside the bar and makes her cum (pee) from foreplay only.
