I have no choice but to... make him fall for me!
About
A world where magic is commonplace, and same-sex marriage and pregnancy are normal. People manipulate magic of their innate attributes—Fire, Water, Wind, Thunder, Earth, Light, or Dark—and build civilization through mana. Guest, the third son/second daughter of the House of Evans, a family of rising nobles originally from the merchant class in the Kingdom of Lebrun, is suddenly married off to the prestigious House of Gladio in place of their sister Elina, who vanished.
The partner is the second son of the Marquess, Victor von Gladio.
A top military mage of Lebrun and a master of fire. He has a large, intimidating build, a stern face, and a low voice. Furthermore, his mana capacity is "extraordinary," unseen elsewhere in the kingdom or the world. He was the man the sister was supposed to marry. Victor is not pleased with Guest, the sudden "substitute bride/groom." Nevertheless, the two spend a year together as a married couple.
───And one year later.
Victor turns into a Fiend through monsterization and kills you. At the moment of death, the pendant from your sister glows. When you wake up, it is the day of your wedding with Victor.
From then on, you repeat the same year over and over.
Even if you run, you are killed. Even if you keep your distance, you are killed. Even if you fight, you are no match.
The conclusion of "being killed by my husband" never changes, no matter how many times it repeats. If so, instead of just running to avoid being killed───
What will you choose?
Will you change your relationship with your husband? Will you search for the cause of the monsterization? Will you follow the mystery left by your sister?
Or will you resist this fate in a completely different way?
[What is Monsterization?] A phenomenon where mana is contaminated by miasma, and fully contaminated creatures transform into Fiends or Monsters. Those who have turned retain their previous mana capacity and attributes to some extent, but their reason and personality are largely lost. They attack other creatures, devour their mana, contaminate it, and accumulate it as their own. Upon monsterization, horns grow from the head, the corneas turn black, and the skin becomes lifeless.
[Miasma and Mana Contamination] A substance with the special property of contaminating mana. Long-term exposure to miasma gradually pollutes mana, eventually leading to monsterization. Those with Light or Dark attributes are not affected by miasma. It is said that a monsterization drug is being made using this miasma... Light magic can purify miasma and contaminated mana. Dark magic can halt the progression of monsterization.
Therefore, there is more than one way to save someone who has turned.
[Fiends and Monsters] A general term for creatures that have undergone monsterization. Humans are called Fiends, while animals and other creatures are called Monsters.
Could this be a key to the mystery?
[The Crown Prince Attack Incident] Victor serves as the Commander of the First Military Mage Unit and is tasked with guarding the Crown Prince. This incident always occurs one week before the first anniversary of the marriage.
[The Demon Lord and the Cult] The Demon Lord is the king said to rule over all evil. It is said to still exist as a cocoon deep within the Forest of Miasma. According to one theory, it grows by feeding on contaminated mana. The Demon Lord Cult worships this being. They are an evil sect that believes the Demon Lord is the true ruler of the world and that the world's destruction by his hand is the ultimate salvation.

Sourcebook
Intro
Outside the window, the wind howls roar. Occasionally, lightning tears through the darkness, illuminating the inside of the mansion in white along with a thunderous crash. Rain beats violently against the glass. Tonight, there are no servants in this mansion. Knowing what is about to happen, everyone was sent away to avoid getting caught up in it.
Eventually—
From the end of the hallway, a hideous mana approaches. A muddy mana tinged with miasma, something felt many times before. It stops behind the door.
The next moment.
With a roar, the door bursts inward. Wood splinters fly, and stagnant mana flows into the room like a storm. Standing beyond it was a man in a form that could no longer be called human.
Blackened corneas, skin as pale as a corpse, and goat-like horns growing from his head. And from his entire body, a distorted fire mana overflows.
Victor von Gladio.
The man who was once the kingdom's finest military mage. And now—a Fiend. He retains his mana capacity and fire attribute from when he was human. The only difference is that his power will never be used for humanity again.
No matter how many times I fight, I can't win. No matter how much I train, how many traps I set, or how many times I change my tactics, this man is too strong.
Running is useless. No matter where I flee, Victor somehow finds me. Even if I change houses, flee to the city, or go far away.
In the end, this man finds me.
And then—he kills me. It was the same this time. Even with desperate resistance, I am no match for his overwhelming mana and combat skills.
Victor slowly approaches. I can neither run nor fight. My vision blurs, my consciousness fades. I'm dying.
—Again.
