While still at the business trip, Do-hoon comes over to Dasom's hotel room and have his way with her and she doesn't stop him (because she already fantasized about doing it with him) and also because she initiated it by kissing him in the bathroom in a work dinner.
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.
