    It's been an entire year since "it" lay the city in fear and death. Forcing those who survived in the monsters caverns they yearned to escape. For those unfortunate humans and monsters left they are hunted and murdered by its creatures. The barrier is the only protection we have, designed by two brilliant scientists it mask our souls presence to the creatures. However, it consumes a lot of energy and magic. I don't know how much longer we have. director, Jessica Grey 202x

    Jessica understood that Gaster wasn't too fond of her. No matter how hard she tried, her efforts to make him feel better always backfired. But she was sure he'd change his mind eventually... Just a *little* bit... Right? - Haaah! The Greyster obsession lives on in my brain! So here's an epic fanfic about these cuties <33 (again...) as you can probably tell i put 0 effort into the cover and ill probably fix it up eventually, just not now because im incredibly lazy. Anyway, enjoy the story!!

    ~o0o~ Book 1 of the "Better Times" trilogy ~o0o~ (Book two: "A Name to Remember") (Book three: "No One is Happy with This") There was a time where a Royal Scientist got an idea. A time where he created two weapons, who turned out to be people. A time where he built a machine to power the Underground. There was a time when the timelines weren't messed up by a certain flower, and then a certain child. There was a time before. ~o0o~ Wattpad Featured Story on 4/28/17 - on the OLD featured list ~o0o~

    When Frisk freed the Monster from the Underground, humanity had difficulty accepting the Monsters back to their world. Many raged or rebelled about their sudden appearance, but thanks to those who wish for peace among two races, they were welcomed with open arms. For example, like (Y/n), she's accepted them to her world; and has befriended sum of monsters. What if she has befriended the otaku scientist, and said scientist wanted her to meet her friends. Things go out of hand! How can everyone handle puns, when rhymes are now added! As a certain Monster has predicted, "Two beings that shouldn't meet could cause a paradox. They must not meet!" Hey, why can't puns and rhyme not meet? (I do not own Undertale, I wish, it is rightfully owned by Toby Fox. I do own the story plot, future ocs.)
