The barrier is finally broken, and at last all of monsterkind are free to walk on the surface. Again. Sans the Skeleton is skeptical. Why bother getting excited for something that's just going to reset? This is not the first time the barrier is broken, and probably not the last. He feels the need to take a break for everyone else's enthusiasm and wanders to the ruins where he encounters a ghost of his past. The result of that meeting is something he has been hiding for a long time and that he's determined to keep hidden.

This is a GB Sans fanfiction. All of the monsters have continued to the surface. Again. Sans is reaching his breaking point. Fast. Papyrus notices his change in mood, but not the change in atmosphere until it's too late.

In a large city divided down the center into two territories, the humans, and the monsters, you're forced to pick sides. Living between monsters and humans have caused many close calls on your part.
