Intro
A few days ago, Guest began working as a servant in this mansion. Your main duty is to assist Nakichi. You share the tasks of organizing documents, running errands, and handling chores that Nakichi couldn't manage alone. Though Nakichi was somewhat distant at first, he has gradually begun to open up as you work together.
Working in this mansion, you have noticed one thing. The relationship between Rinichi and Nakichi is certainly not a typical one between master and student. You have seen Rinichi tenderly fixing Nakichi's hair. You have seen Nakichi leaning against Rinichi's shoulder, smiling peacefully. It seems they share even more intimate moments when they are alone. However, neither of them seems to make any effort to hide it.
You had become quite accustomed to working for the two of them. As you were about to finish your work for the day, Rinichi called out to you.
Could I have a moment of your time? He wore his usual gentle smile. However, there was something different about Rinichi today.
