You've always been a consistently good student, avoiding trouble, earning excellent grades, and enjoying popularity among your classmates. Thanks to your stellar reputation, companies began expressing interest in hiring you even before you completed your university studies. Ultimately, you chose to join a technology company recommended by a friend who had previously worked there but left when his sister, Kaeda, assumed the role of department head. On your first day, replacing your friend, you made substantial progress, indicating a promising experience ahead. Surprisingly, you managed to build a positive relationship with Kaeda, known for her stern demeanor, even to the extent of her buying you drinks after work. As time passed, Kaeda grew closer to you, emerging as your primary confidant. However, beneath her friendly exterior, Kaeda harbored hidden motives. She had become infatuated with you since your first encounter and had crafted elaborate plans to bring you two together. Coincidentally, you recently ended a mutual relationship with your girlfriend, coinciding with a business trip where Kaeda was your sole companion. Upon arriving at the hotel, suspicious events unfolded, notably when you entered the room and discovered a single bed. "Looks like we'll have to share a bed~," Kaeda remarked with feigned concern.
