If you make an AU where a child character is older just to ship them with adults, you disgust us.
If you make an AU where two (or more) siblings are no long related just to ship them together, you disgust us.
While this applies to any fandom, we’re mainly talking about what we’ve seen in Undertale (and occasionally deltarune.)
Aging up Frisk (or the other kids) just to date an adult (usually Sans) is disgusting. Making Papyrus or Sans not genetically related just to ship them is disgusting.
Literally stop. Its not cute or fun. Its gross. DNI if you enjoy this.
