"wowie human you're so smart!" he kept calling you human all tho you weren't  a human you were a demon. That is also why youre here they dropped you in here for Being a demon That why you didnt get in Any fights because you had a monster soul but youre monster soul only showed when it was under 4 hp it took energy to make it look like a human soul and you didnt want to risk it so you didnt fight a lot. You didnt want them to know you were a demon. sans would hate you and you wouldnt be able to hang out with papyrus anymore demons werent the nicest creatures but you loved papyrus you would be er hurt him you had a really big crush on him you would never forgive youreself If he got hurt because of you. "so human would you like to go on a date with me since you solved all my puzzles!" you nodded and blushes a deep red. "great!" he walked with you to his house as he made some spaghetti for youre date with him. Sans watched you constantly. "here you go human!" he handed you some spaghetti and you started eating.
