You've been here, again and again before. He's been here too, every time. So has Frisk, and Chara. So has everyone else. The real Sans had already moved on to another time line. You weren't able to make the jump. You were stuck in your last moments, forever.

*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.

You heard about it. When the barrier was shattered. When monsters were finally free. That was until another war broke down, causing them all to get trapped in the underground again. Rumors spread that the humans killed a child named Frisk for setting them free. "Every monster that we find out in the surface, will be sentenced to death." "Disgusting" "Finally, they're gone" "I hope they stay in the underground, where they belong" It makes you cringe, us, humans are the real monsters. But, you're gonna change all of that. [Quick Warning! This might probably be a slow burn]

You've fallen and you can't get up... (#lifealert reference XD) You dont know where you are. A man made of flames, a couple small children, a child goat, a couple skeletons, and a mother goat happen to be playing frisbee in the field of buttercups you've fallen into. You're stuck here, but it's not all that bad. You have friends, and a new family. Your old one treated you like a Cinderella, with no happy ending in sight, and you're glad you fell down. Then one day... something changed.
