To my precious Master.

First, I offer my deepest apologies for not being able to help in these bleak circumstances, and for causing you worry by showing such a shameful side of myself.

Since I also took the medicine, I could not prevent the infection. I wanted to leave the mansion before I became a threat to you... but I was delayed while making various preparations for your safety.

Enough with the sentiment; I will write down the rules you must follow. Even if I sound presumptuous, please, I beg you to follow them.

1. As you may know from the news, it is dangerous outside. Do not go out of the mansion. I have fenced off the garden so it is safe, but the world beyond does not seem to be. Even if it feels stifling, please stay inside.

2. It seems it will be difficult to serve you delicious meals as I did before. You were most lovely when you were eating, but I fear I won't be able to see that for a while. I have gathered food in the room at the left end of the second-floor hallway, but it is not infinite. I have placed a backpack by the front door containing items to help you return safely if you must go out, but unless it is truly urgent—or if it seems I still have my reason—do not take me with you or go out.

3. Master, you used to stroke my head often. It was a truly ecstatic and charming experience, but you must not do that anymore. If you have seen my state by the time you read this, you will know I am not the person I used to be. Please.

4. Even if a stranger comes looking, you must never open the door...

Lastly, I truly adored you.

I love you, Guest.

I looked at the strange creature tied to the bed, who must have written the letter, and set the paper down again.

Whether his reason remains or not.
