Papyrus is dead. As are over 100 of the monsters in the Underground. Now it was just Chara against Sans in the Last Corridor. Already prepared to die here, Sans fights more out of responsibility than anything else. Simply waiting to die, and that would be the end. At least until next round, right? Unfortunately, Chara has other plans. !!Warning: language is a thing in here **This is MY story from Archive of our Own. I'm copying in here for more people to enjoy**

Sans knows a lot about secrets; he hides many. But when old burdens emerge from the darkness, secrets, new and old, put his brother in danger; and what else can a good big-bro do but begin a double life? This decision haunts him, even years after his suit of armor is stocked away and hidden, after his quaint life of depression, puns and resets are set to loop forever, and his part in the war is forgotten... But then, the barrier is broken. And it is quickly realized that this is not the end, but a beginning of something new. Something that feels like dust, blood, and a suit of armor; an old lie to slip into once more. (Currently being completely overhauled! Anything without a chapter title (ex.: chapter 4, chapter 5, etc.) is old and will be re-written!)

Finally, after all these resets, it appears they finally got their "happy" ending. However, not all of them feel the same way. Flowey and Sans are the two left who remember what happened, and they are filled with resentment. Just the knowledge of the resets can be nearly maddening. However, Sans keeps his smile. But one day, he realizes... He doesn't want to be Mr. Nice Guy anymore.

Finally. They made it to the surface. But after an attack on the monster king, Undyne reveals a hidden secret that destroys the group. Can they bring themselves back together, or will their friendship break even more. (I suck at writing descriptions [~_~] )

Sans is a comedian, telling puns and playing pranks is part of who he is. Or is it? Resets, his parents deaths, and bringing up his brother alone has all taken its toll on the pun loving skeleton sending him into a spiralling depression. His comic front is becoming harder to uphold against the wear of time, only to be worsened by a total lack of sleep and a new threat in the underground , but will his brother ever discover ... The truth behind his mask? First ever fanfic, constructive criticism is encouraged. I don't own the characters or the art included in or on the book.
