You worked for the newspaper, doing a simple editing job and a few other things here and there. Ever since monsters came out of the ground, though, rent has sky-rocketed for you. You thought you could deal with it, but after a few months you need a roomie to help with the rent. Which, fortunately, you got one! But, unfortunately, you're too awkward to fucking deal, man. And this skeleton just laughs at you for it. -this fic has lots of cussing in it, and is a slowburn!- -if you have any suggestions of drabbles i should write for the story, comment!- all gaster!sans fics are way too serious to my liking on here, so I made more of a slice of life/comedy fanfic! hopefully this will go well HOOWEE Cover art by junkpilestuff on tumblr!!

You have a routine; jog, relax, and work. It may seem mundane to most, but for you it's comfortable, easy. It keeps you in your bubble. And you wouldn't change anything about it. That is, until two skeletons move in next door, and you discover that their lifestyle is a less than conventional one, but one you're going to have to learn to live with anyway, for better or for worse.

*Discontinued* This is the original version of Can You Hear Me? in it's unedited form. Monsters were back on the surface! But not everyone was happy with the change... though you aren't one of those people! Happy as a (relatively) popular singer, you were oblivious to the growing discontent. That is, until you met Mettaton's friends! The eventful evening changes your life in more way then one, but where you'll end up you don't know just yet. P.S. I do not own Undertale! If I had to give this story an age rating I'd say maybe 14+ or PG 13 I do use swearwords, there is violence, and there may be topics some people aren't as comfortable with. Of course nothing is stopping you from reading, just do so at your own discretion and know I've given you fair warning.

Alone in a condemned world where monsters and humans fight for power constantly, Y/N survives off of the wood's riches and the small scraps of shelter she can find in ghost towns. Allies and friends have come and gone during the war, either killed or have parted ways. It's not all that bad. She could be dead, after all. One afternoon when shipments from the Human Capital come on a train, she meets a mysterious stranger who saves her life. He's a monster, no doubt, a skeleton to be exact. Y/N is intrigued by the monster and decides to follow him into the next town over where he disappears into an abandoned warehouse. Y/N follows him in only to be pinned to the wall for questioning. After answering all his questions, introductions are made and Y/N learns that the skeleton's name is G. Y/N likes G despite his hateful nature and somehow convinces him to let her come along on a quest he's taking to save his brother from the Monster Capital where they took him for war. After surviving assaults, the government, and Mother Nature herself, Y/N and G start to form a special bond that neither of them wants to break. But when everything goes wrong and neither of them is strong enough to prevent it, Y/N finds that the capitals that she had always hated are far more sinister than she could've ever imagined.
