You and Bill made a truce, but with the help of a deal. He will provide you with protection and he will partially get a human form from you

and so you live in a place for 1 month and there is nothing wrong with that, except for an overly annoying and playful mood...

you are watching a movie and Bill is lying on the couch watching a movie too, but with his head on your lap. Then he began to playfully kiss your cheek, standing up in a sitting position

Bill: you are such a cute Dipper! Why are you always like this?~
