And the cover is by SunnyShineSans or @hiqwl_57 on picsart also both of those are literally just me on picsart lol I have a whole other book about my picsart edits.

(I couldn't help myself, I like theses two games all lot so please don't judge and Frisk is still a girl, also Chara is going to be here as a ghost flying beside Frisk (they are a girl as well, she's a pacifist child too :) ) (Picture cover belongs to me) After All the monster's have been Free from the underground, the King and Queen, Asgore and Toriel, needed to have an ambassador on their side when having an Embassy. (Frisk is about 8 years old here okay) Frisk suggested if she could help them, but according to the country's rules, she's to young to be one. So that couldn't happen, Asgore and Toriel would have to leave with the people who made the rules to change it, so they had to leave Asriel and Frisk with Sans and Papyrus's, to take care of them at their new house. (All monster have new houses on the surface). As Sans turned on their old TV, he put on a old Cartoon, "Bendy And Boris Adventures". Frisk told them that, that Cartoon Used to be very popular back then, but she never new it would still be on to this day. As Sans and Papyrus left to get some groceries, both Frisk and Asriel had to stay inside of the house, both kids weren't sure why. But as they looked at the TV, continuing to watch the Cartoon, a knock was heard from the door, they opened it to reveal a old mail with black ink around it, as they opened it, it was pretty old, and it was signed by a person name, Joey Drew. Then a flash of light from the TV opened a portal, as they backed up, they were pulled into the portal. And as they opened their eyes, they were in shocked to be in a strange old building. Note: Looking back at this Yes I have noticed my many spelling mistakes and unnecessary long paragraphs, I could edit them but I'm too busy + lazy :')

So uh, hey y'all. It's me, UnderFell Sans, or Red. Doesn't really matter. This is a journal *cough* diary that I created to document all that happens while our friend UnderLust Sans (or just Lust for short) is um, "visiting" us? Eh, that's not really a good word to use. "Being held hostage?" Anyway, hope all you kids like it.
