    How Papyrus and Sans deals with Sans running away. Maybe their lives will intertwine again. This is an alternate version to the AO3 story 'April Fools'. In the orginal, Sans stays. In my version, Sans runs away. Enjoy!

    ((DISCONTINUED)) After Chara erased the timeline, everyone had to go somewhere. That somewhere for Sans just had to be the Underfell universe. The people of snowdin in this universe aren't very friendly, and when Sans bothers people by looking for his brother, he has to be saved by his Underfell counterpart. Even under the care of someone stronger than him, how long will it be before Sans perishes?

    Red is the "princess" of a prosper kingdom, but at the death of his father, he is forced to find a husband who can rule with him. The choice is difficult when all candidates are unbearable and arrogant nobles. Or are they? The art in this book does not belong to me.

    Ink!Sans and Error!Sans gave me a bit of the Anti-Void to use for this, so that's where I'll be hanging out most of the time. So basically, my admin says that this is gonna work a bit like a Tumblr Ask blog, but she can't draw worth a goat's ass. You guys can comment stuff (questions and dares) and I'll do it. Just gotta make sure Boss doesn't find this book. Uh, Admin says I gotta credit the cover so, um.... Cover by Jakeinimations/Jakei95.
