The Secretary of the Demon Lord

Fired from your job at the whim of your boss's mistress? Called a "gray mouse" and predicted to grow old with thirty cats? Relatives demanding you pay yet another loan for your younger sister because she's a delicate beauty, while you are the workhorse? Is that really a problem! Let me tell you: "No!

Because ending up in another world at the will of a lost soul of a demoness and trying to reform her son, who is predicted to become a high-level villain — that is indeed a problem! And not just to reform him, but also to marry him off in the shortest time possible! Well, since I've been appointed as the secretary to the demon and tasked with organizing his personal life, let's get started. Remember, mother, about your friends' daughters. Let's go through the list. Your horned son might be interested in someone!
