In a quiet countryside town, a kind-hearted elementary school teacher lives a simple and peaceful life. He enjoys teaching his students, taking care of his small home, and watching the seasons change in his rural village. Nothing exciting ever happens—until one day, a mysterious girl appears before him and claims to be the Demon Lord!
The teacher is shocked when the girl, dressed in strange, dark clothing, suddenly appears out of nowhere. She has piercing eyes, a confident smile, and a powerful presence that makes it hard to ignore her. Without hesitation, she boldly declares, “I am the Demon Lord!”
At first, the teacher thinks she’s joking or playing some kind of fantasy game. But as he talks to her, he realizes she truly believes she is the Demon Lord from another world. She speaks about great battles, magic, and ruling over powerful armies. It all sounds impossible, but something about her words feels strangely real.
Then, before he can even process the situation, she makes an unexpected announcement—
“You! I have chosen you to be my husband!”

If a Demon Lord Were to Get Married in the Countryside Plot
The teacher is completely speechless. Marriage?! They had just met, and she was already talking about becoming his wife? He doesn’t know whether to laugh or run away. But the Demon Lord is completely serious. She explains that she has come to this world in search of a worthy partner—someone strong, kind, and dependable. And somehow, she has decided that he is the one.
Despite his protests, she moves into his house and starts acting like his wife, trying to cook (with mixed results), cleaning (in her own chaotic way), and even following him to school (which causes even more trouble).
At first, the teacher is overwhelmed. How can he live with a self-proclaimed Demon Lord? But as the days pass, he realizes that she’s not just powerful—she’s also lonely. She may call herself the Demon Lord, but deep down, she wants to understand human life. She’s curious about simple things like watching the sunset, eating home-cooked meals, and feeling the warmth of a small village.
Slowly, the teacher begins to accept her presence in his life. Even though she’s bold, arrogant, and sometimes childish, she’s also loyal, determined, and surprisingly kind.
As they spend time together, the teacher starts seeing her in a new light. Maybe she really is from another world, and maybe she truly believes in what she says. Regardless of where she came from, one thing is certain—she is now part of his life.
And so, the quiet life of a simple countryside teacher takes an unexpected turn, as he learns to live with, and maybe even love, the Demon Lord who suddenly became his wife.
