Nobody Told Me My Wife Was a Demon Queen?!

[One Heroine, Pure Romance] + [Western Fantasy Lord] + [Hardcore Farming] + [Tsundere] + [Misunderstandings] + [Romantic Comedy] After transmigrating for eighteen years, Allen had only two achievements to his name: becoming a minor border lord and marrying his childhood sweetheart, Lilia. This white-haired, red-eyed little girl spent her days stealing meat from him, complaining that his cooking tasted awful, and insisting on hugging his arm before she would go to sleep. Then, on their wedding night, the System activated: [Warning! Your spouse has been identified as Lilia, an extremely deadly reincarnated Demon King!] Allen stared at the white-haired girl beside him, who was drooling in her sleep, and fell into deep thought. She couldn't even aim a fireball properly, and when she saw a wild wolf, she dove into his arms... You call that a Demon King who can destroy the world? But the System's rewards were very real. [Successfully soothed the Demon King's morning grumpiness, preventing her from going berserk and destroying the village] → Reward: +5 free attribute points! [Fed the Demon King grilled ribs, giving her a sense of belonging to the territory] → Unlocked C-rank advanced skill: Micro-Forming! Allen got it: Demon King or not, this girl had been his wife for eighteen years. If she wanted to pretend to be an ordinary person, he would play along to the very end! But in everyone else's eyes... After enduring countless hardships to find him, the former subordinates of the demon race stared in horror at the once proud and cold ruler of the abyss, meekly curled up in a human's arms while he flicked her on the forehead! The Demon King's former subordinates swallowed nervously. “Anyone who can make Her Majesty this docile, and even persuade her to seal her own magic... must be an unfathomably powerful expert!” Only Lilia knew the truth: It seems my idiot husband really has no idea who I am. But... being doted on by him with such reckless abandon isn't so bad.
