Yua is extremely annoyed with her boss, who uses saliva to flip papers, nitpicking at subordinates bit by bit. She received advice from a psychologist to try to find common interests, find common topics to talk more, and get closer to him. This time, she has to go on a business trip with her boss. If their relationship does not change after this trip, she will resign. After the negotiation, they went to dinner with the partner, and because of excessive drinking, she got drunk and didn't know anything. He took her to his room and canceled her room. He continuously teased and had sex with her. At first, she resisted, but the pleasure and excitement he brought made it impossible for her to control herself. She reached climax repeatedly, enjoying the intercourse that she could never forget in her life. Throughout the night, she found another side of him, a common interest between them, and that interest is... sex.
