~Sans POV~

We parted the kiss, Frisk placed her head on my chest and yawned. "Ya' sleepy princess?" I asked, stroking her fluffy brown hair. She nodded in response. Without warning her, I teleported us to her room. "Sans!" She said, trying to raise her voice. "Calm down princess" I said. I carried her bridal style and lay her down on the bed. I pulled the blanket over her and gave her a peck on the forehead. She smiled as I sat down beside her.

Frisk kept flipping pages, suddenly, three pages slipped out of the book. She was able to get all of it. She got curious and read the pages.

Whoever is reading this, please bear with me.

Reader, I am King Gaster, I have two sons who will not forgive me if they knew what I am going to to do. Dr. Alphys, the royal scientist, made me a machine that can read the future. She warned me, "you can never change the past your highness which, is today in the future." I tried the machine and was shocked to know my kingdom will fall beneath the mountain, Mt. Ebott. I knew it was a bad idea to make the castle there. Unfortunately, I didn't listened to Dr. Alphys' warning. I searched through my own lab something that I can use, something I can do to protect my kingdom. Finally, after years of searching I have finished my made the perfect machine. It can make a person go back through time. But with my clumsiness, I accidentally hit the cup of coffee to the machine. Wires tackled and electrified me. I turned into a soulless monster who needs a soul...of a human.

Frisk started reading the next page.

Alphys saw me and gasped, as soon as she did, she ran to her lab and gave me potions of such kinds. But It only became worse. People can't understand me, I started hated everything I see...even, my two sons. Without thinking twice, I started killing monsters. Alphys locked me in a dungeon, without telling my sons and my kingdom. My people keep asking "where's our king?" No one can answer that question. 13 years later, my two sons took over the kingdom, but, as part of the rules, my eldest son should marry the eldest daughter of the neighboring kingdom. Unfortunately, Sans, my eldest son, refused. "I can't just marry a girl who I don't even know! Dad will understand!" He said. Alphys said she tried to reason with him, but he won't just listen. Then, the conflict happened at midnight. My kingdom started rumbling like an earthquake has happened. My kingdom sank at the bottom of the mountain and it disappeared without a trace. Hopefully, everyone was safe.

Frisk read the next page. It was a little crumpled.

Reader thank you for reading this. If your wondering how I know all of this? Well, I used the machine to read the future and I was able to write all of this. If your one of my sons, please forgive me for this, Sans, Papyrus...I will understand if you won't, also your mother.

Frisk gasped when she saw a figure. She hid the paper at the back of the book and pretended she still kept flipping pages. She felt a hand on her shoulder and turned, "Sup princess. You found the right page?" Sans said. Frisk forgot all about the papers.
