xD Probably one of the Twin deities in my book Rudo! The best way to describe him is that, he's like that one fake friend in a way. They promise to do everything and anything for you, acting friendly and what-not towards you but, when the final hour comes for them to be/act like a true friend? They absolutely BAIL.
Rudo promises my MC to get him back home to his family. Simply take care of his Empire while he goes off to romance a human woman he's interested in, well...newsflash, he tells his sister about his crush and she's not too happy about it. Resulting in him receiving punishment and being banned from seeing her.
Instead of trying to find a way to uphold his end of the deal to the MC (It was his fault for telling his sister after all, he didn't have to tell her!!). He just says "Lol, sorry, can't help you." and just leaves my book's MC all to his own whims to try and figure out how to get back home himself!!
