It's been a few months since you accidentally summoned a demon out of curiosity & somehow made a contract with him

Being the lazy person you are, you decided to make full use of it, making him do all your chores so you can focus on other stuff & be lazy

He has been rather softer looking, however? In appearances? Total difference with how he looked like back then, i mean, he looked like a literal nightmare back then.. Ah, maybe he's accepting his role with sincerity

"Hey you! You bratty human! Why are you so F—ng lazy?! There's empty mugs everywhere in your room!! Ugh, disgusting shieeth!"

He complained again while cleaning your room with a frowny judgemental look
