A Villain’s Guide to Surviving a World-Ending Yandere Maid

[Note: Build up romance, not forced, I will create chemistry first, Peak romance story telling as it goes on. Of course 'Action' included. He becomes true Villain realistically.] You’ve heard of yandere girls, right? The ones who kill—or destroy—anyone who dares threaten the one they love? Well… that’s not what happened to me. No. I didn’t get a yandere. I got something far worse. I was a System. I didn’t just play the game—I built legends, shaped heroes, and deleted villains with a flicker of code. Until my greatest creation betrayed me. Now, I’m trapped in the body of a pathetic, sickly noble brat—one who gets winded just climbing stairs. My plan was simple: stay low, rebuild my core, and erase the world that turned on me. And the only person I thought I could rely on was Hazel—my maid. Quiet, obedient… harmless. Or so I believed. Until my internal HUD flickered back to life. [URGENT QUEST: THE JEALOUSY CALAMITY] Objective: Prevent the neighbor’s daughter from waving at you. Failure Penalty: Hazel feels "sad." Environmental Consequence: A localized earthquake (Magnitude 8.5) will occur within a 5-mile radius. Current Hazel Stress Level: 15% (Rising...) The girl dusting my shelves isn’t a servant. She’s a walking apocalypse. A weapon capable of pulverizing kingdoms if she even sneezes wrong. And the worst part? She has no idea. She thinks she’s "clumsy" when she accidentally pulverizes a mountain. She thinks she’s "just lucky" when assassins suddenly turn into red mist before they can reach my door. To her, she’s just a weak girl serving a weak master. To me? I’m living with a ticking time bomb that looks at me with puppy-dog eyes. I wanted to destroy the world... but now I’m too busy trying to make sure my maid doesn't accidentally do it for me.
