The Door (Toriel x Sans Fan Fiction)
Sans the Skeleton watches for humans for his brother Papyrus when one day, he sees a door. He walks up to the door and does knock-knock jokes. Unknowingly, he finds he has an audience. She answers. Then it's her turn. The two keep going, laughing their heads of. And before the could stop it, the began falling in love. But, the woman on the other side, Toriel cannot open the door in fear the child could get out. Or even worse, maybe the person on the other side mightn't like her., or recognise her. Some say love is simple. That is wrong.
The two leant on the door, bearing a heavy sigh. "The door is only thing stopping us from finding out who is on the other side." The pair said in unison.
