Saika and Akagi are dating, but since they work in the same department, they are keeping this relationship a secret. Akagi is a competent and kind person, always caring for Saika. She also imagines the day they will live together. Manager Takeda knows everything; he has noticed Saika for a long time, and this business trip is the perfect opportunity for him to win her over. There are many unpleasant rumors about Takeda, so Akagi is very worried about Saika. On the other hand, having been Takeda's assistant for a year, Saika trusts him greatly. And then that day arrives. When dining with partners, she is continuously pressured to drink, causing her to doze off unexpectedly. When she wakes up, she finds herself being taken to a hotel by Takeda, and he will share a room with her tonight. Her mind tells her to resist him, but her body doesn't have any strength at all. Takeda's bold thrusts brought Saika to the peak time and time again, giving her a pleasure she had never known before. This feeling gradually took over her mind, making her forget about her boyfriend who had devoted himself to her but chose Takeda instead. After returning, Saika immediately broke up with Akagi, and when they met again at the company, she only regarded her boyfriend with all her heart as a stranger, because now she devoted both her mind and body to the department head.
