I'm Fine (An Undertale Story)
Sans is living comfortably on the surface, or so everyone thinks. After he is left alone with his thoughts and many tragedies occurr, All his friends, and even his brother, are starting to question what they know about Sans.
"Are you okay Sans?"
"Well, we have seen that you've looked a little sadder ever since Papyrus moved out of your place and into mine and Alphys's place."
"nah, don't worry about me. It's just been a little emptier in our house, and sure i'll miss him, but we'll still see each other."
"Why didn't you say ' i'm a little bonely ' instead of ' i'll miss him '?"
