Sans has always been treated like a child. With his small figure and adorable features. He feels frustrated that he can't be treated like everyone else. His brother is probably the worst of the bunch. Papyrus always tries to protect him from everything. All Sans wants is to become an adult. One night he'll get exactly what he wished. Except that it won't come easily.
Maybe it'll be something he'll regret.
