After the modeling shoot was over, Do-hoon and Park Da-som were all over each other in the waiting room at the studio, Ye-eun having been in the room before they got there, hides behind curtains and watches them enjoy a very good shagging with multiple positions.
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.
