Why is this timeline wrong? Is this meant to happen? . . . . Is there really a happy ending to begin with? Being a swapped universe doesn't make it a lot different from the other timelines. It is almost the best timeline you could ever have. But... why? Why does it have glitches? Why do things appear in where they shouldn't be? Whose fault was it?.... Are you also tired of being kind? . . . . . . . . . . . . . . . Sans?

I walked through the halls, then stopped. I peered into the eternal darkness, trembling. I could only stand still. I shook, hearing screams of agony. I could only stay there, until dust drifted past. "What have I done. ." I was cut off from my thoughts. "You're not supposed to be here~" ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This is an undertale multi-verse story. Blue loves all his friends platonically, but when will he realize he loves one of them more than words? {COARSE LANGUAGE} {GORE} {SELF-HARM} {Depression.} Btw guys, this is my first story. And cover art does not belong to me, I kinda suck at drawing. Have fun reading this story! -Fluff
