Dear Sans,
I've lost count of the days. I couldn't tell you what day it is. As much as it hurts, I'm losing hope too. But I hold on to the thought that maybe, maybe, the human will reset. I miss you.
But Sans, I'm so proud of you. You've been working so hard to find any other monsters in the Underground, despite the loss of your hope and the slowing of your step. I see you sleep in the lab below our home. Your HP is dropping, even with what little you have.
I'm afraid that you'll join me sooner than I had hoped. You won't even make puns anymore.
