Hello. To get the perfect ending or the Best ending, at the start of the game when she is at your door, DO not lock the door because that's will waste her time and gets mad a lil bit and then don't Pick the paper that from the gevomernt, and say "it's from one of the science" and then watch horror movie with her then COOK her honny toast and DO NOT PICK THAT KNIFE. give her a gift and choose "Nothing" after she said "did I hear you scream? What was it" then Yap about her and say yes after she transform and chose "your a devil" after she said "what do you think I am?"
And then here you go BEST ending!.....
Hopefully this helps😁
Damn I was yapping to mush wasn't i?😭
