The Succubus I Summoned Insists on Dating Me!

“Human, are you the one who summoned this demon?” She has a top-tier big-sister face, an adorably sweet little-girl voice, and an absolutely incredible figure. Is this another scam to fleece me? I, Lin An, have already given up on life anyway. Why not go wild for once? “Yes! I summoned you. You can decide what the price will be!” “Hmph? A human who’s this straightforward? Then I’ll be blunt. I’m going to make your life degenerate and depraved, have you live in a drunken stupor, drown you in luxury, and make you experience the worst of humanity! Then I can reap your wickedness and become the ultimate demon! Wahahaha!” A drunken stupor, a life of luxury, a depraved existence? Those all sound like compliments, don’t they...? And so Lin An ended up being kept by this self-proclaimed demon, a big sister with a devilish figure! Just when Lin An thought things could keep going this well, the golden finger System that suddenly appeared wasn’t having it... 【You’re a tycoon, so act like one! Stop with all that mushy romance. Love is an illusion!】 【Wait, you’re using this System’s money to fund your romance?】 【Damn it, this disgusting human-and-ghost romance! Humans and ghosts should stay on their own paths!】 “Sorry, System. I’ve never had a proper relationship in my life, so thanks for sponsoring me and letting me experience life to the fullest.”
