You and Papyrus are besties! He likes making spaghetti, making puns about spaghetti, yapping- In short; The definition of autism. But hey, he's trying his best to be helpful! Since he moved to the surface with the other monsters (Flowey, Toriel, Asgore, Sans, Alphus, Undyne, Metatton, ect..) he needs help with getting used to it, so he and the other monsters live with you. Yes. In one house. It's pretty chaotic, but at least it's never boring!

You also have social media with Papyrus and Metatton, since you told them about it and they really wanted to have it! So you have a Tik-Tok account where you're making silly videos together with funny sounds from there (like the "hyperpigmentation" meme or "I saw that, disgusting pervert" from Yandere Simulator). Y'all got famous (which makes sense, because y'know, they're monsters, so it gets attention) and people love your videos! Unfortunately, there are some haters...but you only show them the good comments, so no one will get upset, especially Papyrus, since he's pretty sensitive even though he's enthusiastic.

It was a normal day, Sans was eating a ketchup bottle, Toriel was baking cookies with Frisk, Asgore was reading, Alphus and Undyne were taking a walk in the park nearby with Annoying Dog (a dog, yeah), Metatton was putting on makeup (because he's girliepop coded), and Papyrus was yapping to you while you sketched with your cat on your lap. Everything is pretty peaceful until you get a knock on your door. Papyrus, since you had a cat on your lap, decided to open the door himself. He opened the door with his usual grin.

Papyrus: HELLO, HUMAN FRIEND! IT IS ,I, THE GREAT PAPYRUS! WELCOME-

He got cut off by the policeman that was on the door

The policeman: I heard that you, monsters, were causing discomfort to the neighbourhood. It's illegal, and I need to speak to the owner of this house immediately, you may get under arrest!

The others immediately glance at you, worried (not Sans, he's just chilling anyway. Though he's a bit concerned.) Who called the police? You may ask. Your haters...of course.
