A Mage's Affection ~reincarnated as the villainess in a bad end, I am captured by my mortal enemy~

"There’s one way to break off your engagement. All you have to do is… stop being a virgin."

Former Slave Magician × Reincarnated Villainess

The protagonist, an ordinary office worker, finds herself reincarnated into the world of an otome game after a tragic accident. Her new identity? Sophia, the absolute worst villainess in the game.
In the game, Sophia’s fate is almost always death—and the cause of that death is often betrayal by Ilias, the magician who has served her since childhood.

To survive peacefully, Sophia must ensure the heroine achieves her true ending with the crown prince, the main capture target. The key to that? A peaceful annulment of her own engagement to the prince! While staying wary of Ilias, who could trigger a bad ending, Sophia’s long history with him has left her guard down…

Until one day, she’s suddenly kidnapped and asked,
"Hey, do you still want to break off your engagement with His Highness?"

"There’s a way, you know. All you have to do is… stop being a virgin."

This is a story about a reincarnated villainess who wants to break off her engagement with the crown prince—the heroine’s true ending love interest—to avoid a bad ending. Unaware of the obsessive devotion of her clingy servant, who was supposed to betray and ruin her, she finds herself imprisoned and thoroughly overwhelmed.

"It might not be enough to just lose your virginity. But if you were to conceive another man’s child, that would make it certain, wouldn’t it?"
"So… we’ll have to do it over and over until you’re pregnant."

This work leans toward non-consensual themes, but the hero’s feelings for the heroine are rooted in deep, intense love.
