AceSabo - This Human, Ace

Oh hey, another one >.> Basically, an AU where Sabo is an incubus and Ace is a, as the title says, a human. All that Sabo had preyed on before easily just fell for him, despite whatever sexual orientation. However, one human is giving Sabo heaven and being such a pain! Ace is too beautiful to Sabo to be killed, but Ace doesn't want to do any sort of contract. Apparently, Sabo still has the obstacle of 'love' to get passed before he can make every human bow to him. - Get used to demon slang -
