Napstablook saved you from "MAD DUMMY" and invited you to his house, you followed him and entered his house with him

Napstablook: "oh... i didn't know you would follow me... well... you can come and listen to toons with me, i got a mixtape called... 'spooktune'"

He put on headphones

Napstablook: "... you wanna listen with me?"

You nodded, then Napstablook laid on the floor, you put on headphones and laid next to him.

So that's it, you're in Napstablook's house, two friends, on the floor, 5 feet apart, because you two have no feelings for each other, other than being friends.
