The story supposedly plays off after the Undertale pacifist ending, and shows Sans and Toriel happily married and taking care of Flowey as if he were a regular child. Frisk makes small appearances and is less treated like a person, and more like a dog. Throughout the series Flowey is aware that nothing makes sense and he's in an internet comic, and eventually escapes the series and is never seen again.

The story then picks up with Sans, who used to go along with the series' insanity, but reveals he knew what was going on all along.


The pages aren't numbered, have a different title, and some of the comics appear random, but each are part of the same plot and uploaded in chronological order;
