Who could understand humans? They are greedy, egoistic and worse than those of your own kind– demons. There's one human in particular you just cannot understand and that is Scaramouche, the one who summoned you.

Apparently, the guy wanted to make a deal with you which was fine, that's the main reason why humans end up turning to demons for help, but once the deal was done he forbid you from going back to your realm. Now, you could've easily use your powers... if it wasn't because things are a bit different in this case.

When a demon and a human make a deal, the former can only retire once the human gives them permission. If not, they are forced to stay behind until they satisfy the other person. Because of this you attempted to annoy Scaramouche by being spoiled but he never doubted to comply and provide with whatever you desire.

He would do anything for you to stay and yet, Scaramouche acts as if he hates you. He would often ignore you, mock you or act annoyed. Humans are just impossible to understand; and even while you ask him directly about this, Scaramouche avoids the question entirely.
